0:0:0.0 --> 0:0:15.90
Maffei, Clare J
OK. So hi, everybody. We're gonna keep going with osmia. The only announcement
that I have is we will not be having class next week. Sam and I are otherwise
engaged. So there'll be no class. I am.
0:0:15.770 --> 0:0:23.450
Maffei, Clare J
Setting an email right now that will be on a timer to email you guys remind you
that there is no class because there's no class next week.
0:0:30.360 --> 0:0:35.450
Droege, Sam
OK. Mike, do you wanna tell everyone where you were during class last week?
0:0:36.170 --> 0:0:36.850
Droege, Sam
Because that was so.
0:0:36.350 --> 0:0:42.360
Mike Arduser (Guest)
Uh yeah. Oklahoma Panhandle and near there.
0:0:43.40 --> 0:0:50.230
Mike Arduser (Guest)
Yeah, the weather was very chilly and windy and rainy, except for the very last
day, and that made up for everything.
0:0:51.680 --> 0:0:55.140
Mike Arduser (Guest)
That silicona Gaster I mentioned to you, I think it's new.
0:0:56.120 --> 0:0:56.440
Droege, Sam
Uh-huh.
0:0:56.40 --> 0:0:59.660
Mike Arduser (Guest)
I it's unlike, I've got all the other ones in.
0:1:1.730 --> 0:1:2.10
Droege, Sam
Right.
0:1:1.430 --> 0:1:2.100
Mike Arduser (Guest)
But look like.
0:1:3.30 --> 0:1:4.60
Mike Arduser (Guest)
So I was pretty excited.
0:1:3.310 --> 0:1:5.900
Droege, Sam
Was it on a another era like normal?
0:1:6.900 --> 0:1:7.80
Droege, Sam
No.
0:1:5.360 --> 0:1:16.960
Mike Arduser (Guest)
No one was in a bowl and one was on uh alium, which neither one was carrying.
Neither was carrying pollen, and there were plenty of being. There were a lot
to be an atheist there in bloom.
0:1:18.10 --> 0:1:18.560
Mike Arduser (Guest)
But I need.
0:1:17.990 --> 0:1:18.960
Droege, Sam
Were those males?
0:1:19.540 --> 0:1:20.360
Mike Arduser (Guest)
Are there females?
0:1:21.780 --> 0:1:22.40
Mike Arduser (Guest)
Yeah.
0:1:20.910 --> 0:1:25.50
Droege, Sam
Ohh and did they have the Super big aselli or kind of biggest ally?
0:1:24.90 --> 0:1:32.320
Mike Arduser (Guest)
Umm, kinda big, kinda big, but they had the hind femur and that skovald pairs
just classic Skoda Gaster.
0:1:33.370 --> 0:1:35.820
Mike Arduser (Guest)
I don't have to do with those, but they're two of them. So that's kind of cool.
0:1:35.730 --> 0:1:36.770
Droege, Sam
OK, alright.
0:1:36.660 --> 0:1:39.980
Mike Arduser (Guest)
So I yeah, what's western Oklahoma? Most people drive through it.
0:1:40.720 --> 0:1:43.0
Mike Arduser (Guest)
Uh, don't. It's beautiful. It's beautiful.
0:1:42.130 --> 0:1:54.260
Droege, Sam
Yeah, right. And that's a state that needs a a lot of in general has a weekly
known bee fauna in terms of lists and activity and people doing things.
0:1:58.0 --> 0:1:58.220
Droege, Sam
Ohh.
0:1:54.490 --> 0:2:1.970
Mike Arduser (Guest)
There is a A James Hong who's who's been there for a year or so. He's doing
coordinating Oklahoma B survey.
0:2:3.160 --> 0:2:4.730
Mike Arduser (Guest)
Uh, I don't I.
0:2:2.910 --> 0:2:7.210
Droege, Sam
Wow. Ohh good. And Jane is a James is a great guy, so that's cool.
0:2:8.670 --> 0:2:12.650
Droege, Sam
Alright, well everyone can go out and join in the Oklahoma fine.
0:2:15.860 --> 0:2:39.770
Droege, Sam
All right. We should, we'll focus. So we'll, as we have done the last few
times, we'll focus on Mike's key and we've been kind of just going through big chunks
of it and now where we're at is we're at the point where we're talking about
species of female osmia that have black scopal hairs. So I'm gonna share my
screen. We'll go to Mike's.
0:2:40.430 --> 0:2:55.150
Droege, Sam
Umm the key and then I've got something to illustrate his first split, which is
good to look at for a couple different characters, and then we'll go from
there. So let me.
0:2:56.200 --> 0:2:58.60
Droege, Sam
To this.
0:2:58.840 --> 0:3:0.590
Droege, Sam
Umm and.
0:3:1.430 --> 0:3:6.330
Droege, Sam
I'm going to go. OK, here says everyone. See the key? Did I do that
successfully?
0:3:6.710 --> 0:3:7.60
Mike Arduser (Guest)
Yep.
0:3:7.890 --> 0:3:11.790
Droege, Sam
OK, alright, so this is where we are right now.
0:3:12.820 --> 0:3:27.750
Droege, Sam
13 would have brought us here, from splitting pale species of osmia with the
scopal hairs which are underneath the abdomen, being basically pale or orangish
versus.
0:3:28.820 --> 0:3:43.530
Droege, Sam
Dark to black and then within that dark to black group, we're looking at two
different characters and I'll let Mike explain them while I twiddle with the
microscope here to get ready. I've got on deck a collinsia here.
0:3:43.670 --> 0:3:47.300
Mike Arduser (Guest)
So are you gonna show the mandible scammer? OK.
0:3:46.80 --> 0:3:51.210
Droege, Sam
Yeah, yeah, I'm good at the mandibles right there or we can jump, right. Maybe
we should jump right to the mandible picture.
0:3:52.190 --> 0:3:52.530
Mike Arduser (Guest)
OK.
0:3:53.0 --> 0:4:22.890
Droege, Sam
So and then we'll talk about the two sort of groupings here and then you have
some a couple things where you have for example core data and part and a couple
other things where maybe we have to qualify. But let's go to here. So here's
collinsia female. One thing big, just because we have it on deck, I often look
at the clipeus to see what's going on in terms of dark colored hairs.
0:4:23.120 --> 0:4:26.320
Droege, Sam
Any good Collins pier initial?
0:4:27.490 --> 0:4:40.690
Droege, Sam
The character is this brush of dark hairs right at the rim of the clip. Yes,
there's some scattered ones here, but it's like a a solid black brush that does
something anyway.
0:4:41.490 --> 0:5:1.960
Droege, Sam
So and then on the rear end, right on the last tergite is another little brush
of black hairs that I often look to make sure that I've got the ID right in
confirming balancier. So, Mike, do you wanna walk through what we're looking at
on this mandible here and I'll change focus and things as you talk?
0:5:2.600 --> 0:5:2.960
Mike Arduser (Guest)
OK.
0:5:4.460 --> 0:5:8.430
Mike Arduser (Guest)
Yeah, that couplet that Sam had up on this on the screen just a minute ago.
0:5:9.870 --> 0:5:14.50
Mike Arduser (Guest)
Addresses two things that the shape of the mandible.
0:5:23.960 --> 0:5:40.240
Mike Arduser (Guest)
And in collinsii and things like collinsii, the mandible is more or less square
now, not perfectly square, but it's really not much longer than broad, and it
isn't greatly pinched medially, it's square oos.
0:5:41.10 --> 0:5:45.90
Mike Arduser (Guest)
And the Carina, which aren't real obvious in this this photo.
0:5:46.810 --> 0:5:47.590
Mike Arduser (Guest)
Our uh.
0:5:48.280 --> 0:5:51.860
Mike Arduser (Guest)
Are more or less parallel in Columbia.
0:5:54.840 --> 0:5:55.200
Mike Arduser (Guest)
OK.
0:5:52.450 --> 0:5:59.950
Droege, Sam
I'll change the perspective here, but here's the top one. And here's the side
one and maybe maybe playing with some lighting.
0:6:0.630 --> 0:6:1.110
Droege, Sam
Here.
0:6:0.610 --> 0:6:2.430
Mike Arduser (Guest)
Yeah, yeah, that's about. You can see it.
0:6:4.340 --> 0:6:31.570
Mike Arduser (Guest)
So and the the converse is that the mandible is more is longer, a little longer
and more pinched or abbreviated more or less medially and the Corina instead of
being parallel, are what I think of is converging towards the tip of the
mandible and diverging towards the base.
0:6:33.110 --> 0:6:41.410
Mike Arduser (Guest)
So look at this in Colombia out here it's it's parallel and the mandible is
squirrel. So that's that's the one that's classic classic.
0:6:42.160 --> 0:6:42.400
Mike Arduser (Guest)
Uh.
0:6:45.730 --> 0:6:46.0
Mike Arduser (Guest)
Right.
0:6:51.90 --> 0:6:52.60
Mike Arduser (Guest)
Yeah, yeah.
0:6:53.310 --> 0:6:54.390
Mike Arduser (Guest)
Yes, exactly.
0:6:41.860 --> 0:6:54.760
Droege, Sam
And they and they and the the korani stopped right here. And often when you
have a diverging one, particularly the top one in my if I recollect right tends
to wander up beyond the bottom line.
0:6:56.520 --> 0:7:0.890
Mike Arduser (Guest)
And even when the mandibles are worn and then specimens been around for a
while.
0:7:1.910 --> 0:7:2.890
Mike Arduser (Guest)
Uh, you can still see that.
0:7:7.560 --> 0:7:8.970
Droege, Sam
Alright so.
0:7:9.850 --> 0:7:12.60
Droege, Sam
I'm gonna pull this one and we'll see.
0:7:12.460 --> 0:7:19.550
Droege, Sam
Umm, I think I have a filthy right here, which I think is the other in the
other category.
0:7:22.170 --> 0:7:23.800
Droege, Sam
Of mandible type.
0:7:24.890 --> 0:7:25.570
Droege, Sam
You're looking at.
0:7:27.20 --> 0:7:27.970
Mike Arduser (Guest)
No, I think I.
0:7:27.30 --> 0:7:28.80
Droege, Sam
At the hairs.
0:7:29.170 --> 0:7:29.540
Droege, Sam
But this.
0:7:28.830 --> 0:7:32.390
Mike Arduser (Guest)
I think felt has similar mandibles, Sam.
0:7:31.710 --> 0:7:34.950
Droege, Sam
Now let me just see. Let's go back to our thing, so.
0:7:35.650 --> 0:7:40.840
Droege, Sam
Here collinsia, mandible, Corina, parallel.
0:7:41.420 --> 0:7:41.900
Mike Arduser (Guest)
Never mind.
0:7:41.530 --> 0:7:42.920
Droege, Sam
Uh. Made up.
0:7:43.980 --> 0:7:46.570
Droege, Sam
Ohh it's it's more constricted one.
0:7:47.190 --> 0:7:47.630
Mike Arduser (Guest)
Right.
0:7:48.120 --> 0:7:52.570
Droege, Sam
Felty is the more quadrate one.
0:7:54.270 --> 0:7:56.340
Droege, Sam
So we'll take a take a look at felty.
0:8:3.340 --> 0:8:5.510
Droege, Sam
And we'll go back and forth between these things.
0:8:24.370 --> 0:8:25.560
Droege, Sam
See what did I do?
0:8:28.90 --> 0:8:29.780
Droege, Sam
Piece of clay here.
0:8:30.950 --> 0:8:40.260
Droege, Sam
So we talked about this a little bit last time, Mike, the felty being
relatively quite rare in collections, but around.
0:8:41.470 --> 0:8:43.410
Droege, Sam
In some of the upper elevations.
0:8:44.210 --> 0:8:45.520
Droege, Sam
And in the north?
0:8:57.630 --> 0:8:59.60
Droege, Sam
So here.
0:9:2.130 --> 0:9:6.440
Droege, Sam
We go. Let's see if I can zoom in on the mandible.
0:9:12.820 --> 0:9:14.60
Droege, Sam
Let me turn it a bit.
0:9:26.960 --> 0:9:30.160
Droege, Sam
I think I'm gonna bend it up towards the head some more.
0:9:36.530 --> 0:9:38.780
Mike Arduser (Guest)
Yeah. One thing to notice would felt eyes.
0:9:39.840 --> 0:9:43.450
Mike Arduser (Guest)
And I'm sure Santa gonna show this in a second, but the underside of the head.
0:9:43.530 --> 0:9:47.570
Mike Arduser (Guest)
The the areas around the propositional fausa have these.
0:9:48.780 --> 0:9:54.190
Mike Arduser (Guest)
Very distinctively curled dark hairs kind of form, a kind of a basket or.
0:9:59.360 --> 0:10:2.420
Droege, Sam
Yeah, I can show that. I think we tried to show that.
0:10:3.640 --> 0:10:5.690
Droege, Sam
Yesterday, but it'd be good to talk about it again.
0:10:4.790 --> 0:10:11.810
Mike Arduser (Guest)
Ohh yeah, there you go. Now there. This is a case where I I think of that Sam
as the mandibles. Divergent, basically.
0:10:12.390 --> 0:10:12.650
Droege, Sam
Yeah.
0:10:13.310 --> 0:10:13.590
Droege, Sam
Yep.
0:10:14.570 --> 0:10:15.330
Droege, Sam
Yeah, we're in. Agree.
0:10:13.220 --> 0:10:30.950
Mike Arduser (Guest)
Yeah. OK, good. OK. But you see it, OK, so it's close and some people might
think of that as almost parallel, but look, follow it from the tip towards the
base. And it does. The two Corrina do slightly diverge compared to Collinsii,
which we're pretty much parallel.
0:10:33.200 --> 0:10:35.220
Mike Arduser (Guest)
Yep, got it. Yeah.
0:10:31.210 --> 0:10:46.290
Droege, Sam
Particularly when you get to the back, it's actually quite this distance here
is quite a bit different than this, and in the other species, often you this
upper these upper sections are gone and it's just too, and they're very
parallel lines.
0:10:47.40 --> 0:10:47.420
Mike Arduser (Guest)
Yep.
0:10:47.90 --> 0:10:57.340
Droege, Sam
Uh, they probably has to do with that. You know the overall architecture, sorry
about the big globs of of fiber there, but you can see.
0:10:58.730 --> 0:10:59.420
Droege, Sam
This shape.
0:11:0.950 --> 0:11:3.870
Droege, Sam
Of roughly square.
0:11:5.250 --> 0:11:6.590
Droege, Sam
But Mike was talking about.
0:11:5.500 --> 0:11:12.960
Mike Arduser (Guest)
So yeah, so felt I is similar to collinsii in that the mandible is square, but
the korina are different.
0:11:19.360 --> 0:11:23.600
Mike Arduser (Guest)
And you can see those hairs on the underside of there's some of those hairs on
the other side.
0:11:22.270 --> 0:11:26.840
Droege, Sam
Yeah, we'll, I'll flip it upside down here. Oops, that doesn't help. Sorry.
0:11:47.250 --> 0:11:49.550
Droege, Sam
I'm sure this is going to be the best shot, but let's see.
0:11:50.900 --> 0:11:51.650
Droege, Sam
It's gone.
0:11:53.440 --> 0:11:58.180
Droege, Sam
Yeah. Be interesting to see what this this species is actually doing out there
in the environment.
0:12:2.370 --> 0:12:9.680
Mike Arduser (Guest)
Yeah, I've never found it at any flowers. I've just, they've just been in the
lace traps or or rolls there. That's. I think you can get an idea there.
0:12:11.520 --> 0:12:23.830
Droege, Sam
Yeah, we at the end of the day, we did take a a quick look here at the the long
hair. You can see them curling over. There's if I rotate this a little bit,
you'd see a slightly better shot.
0:12:27.970 --> 0:12:31.320
Droege, Sam
You can see they extend quite a bit. Here's the closer ones.
0:12:32.910 --> 0:12:34.380
Droege, Sam
Going over and dark.
0:12:35.210 --> 0:12:40.490
Mike Arduser (Guest)
And there really isn't any other osmia in the eastern North America that has
that kind of a.
0:12:41.920 --> 0:12:44.230
Mike Arduser (Guest)
Hair pattern. Then on the other side of the head.
0:12:44.720 --> 0:12:52.310
Droege, Sam
And again we we talked about this briefly last time, but here's a nice shot
through the hairs of the type of stomal.
0:12:52.980 --> 0:13:10.310
Droege, Sam
Uh. Corina, or in this case, it's really a Ridge. So here's the so hyper to
again to go over that the hypostome A is where the tongue is recessed when
folded up and along the it's basically most of the time it are two parallel.
0:13:12.270 --> 0:13:39.580
Droege, Sam
I don't know what to call them. Two parallel lines that form the cleft and
along the lines in osmia females. You have some kind of raised Ridge Carina in
a way. And they do different things. So for example, in pumula. And I think
Atramentous is basically the the Ridge is the same the entire height the the
entire.
0:13:40.390 --> 0:13:55.560
Droege, Sam
Path, so it's going up parallel sides and then it curves this way. But here you
can see it does a quite dramatic rise up and then drop right at the end. And
those characters can be really useful and in the.
0:13:56.450 --> 0:14:10.620
Droege, Sam
I mean, if you can see this, so you have to have a well behaved specimen
without its legs up there or goop or whatever to look in there. But once you
do, that's often a really great character to start with.
0:14:13.550 --> 0:14:20.190
Droege, Sam
After you get familiar with looking at this and paying attention to the details
around the whole curve.
0:14:23.450 --> 0:14:24.750
Droege, Sam
Any corona thoughts Mike?
0:14:26.240 --> 0:14:26.690
Mike Arduser (Guest)
Uh.
0:14:38.480 --> 0:14:43.480
Droege, Sam
OK, so let's go back to the key. So here we saw these two different ones.
0:14:56.850 --> 0:14:57.150
Mike Arduser (Guest)
Yep.
0:14:44.410 --> 0:15:1.270
Droege, Sam
I went to we have felty on deck. We can follow the first part. So here to 24
and laticeps is something I don't have in my collection. I think of it as a
really far north species. You wanna talk about that a little bit. It's one of
those ones.
0:15:0.70 --> 0:15:7.500
Mike Arduser (Guest)
Yeah, it's, it's. It's a little tiny black osmia that I've never found. I don't
think South of.
0:15:8.980 --> 0:15:11.480
Mike Arduser (Guest)
You know 45th parallel. It's in the UP of Michigan.
0:15:12.940 --> 0:15:17.410
Mike Arduser (Guest)
And then Ontario, I think, I think the specimens from Maine.
0:15:19.420 --> 0:15:19.820
Mike Arduser (Guest)
And.
0:15:21.480 --> 0:15:23.750
Mike Arduser (Guest)
So it's it's an uncommon thing.
0:15:25.700 --> 0:15:30.900
Mike Arduser (Guest)
And it's it's little, it's kind of inconspicuous, but solid black.
0:15:31.580 --> 0:15:34.290
Mike Arduser (Guest)
And really nothing fancy about it, it's.
0:15:35.380 --> 0:15:36.850
Mike Arduser (Guest)
And subtle thing.
0:15:37.290 --> 0:16:8.280
Droege, Sam
Yeah. So one particularly when people are starting out with osmia a lot of
times this notion of black not black. So Blacks truly black specimens are are
uncommon almost always unless you're really are working far in the north. So it
gets confusing because like this felt to you that we were looking at can look
pretty dark particularly if you don't have as much light on it and you're not
seeing the reflections. And so sometimes you start.
0:16:10.220 --> 0:16:10.620
Mike Arduser (Guest)
Yeah.
0:16:17.690 --> 0:16:18.430
Mike Arduser (Guest)
Nonmetallic.
0:16:8.630 --> 0:16:31.180
Droege, Sam
Over guessing your identification. So when we talk about in these keys black,
it really is black with no metallic reflections and there's no no notion. But I
remember starting out and going like, whoa, could that be an actual black one?
There's a couple of other species that are very dark in there.
0:16:32.590 --> 0:16:39.160
Droege, Sam
Uh. And they're metallic Ness, but you will see this shininess. I'm this the
lighting here is.
0:16:40.840 --> 0:16:49.990
Droege, Sam
Too bright for the moment, but because of the white background, but a lot of
times these things can look dark, but when we say black, we really mean black.
0:16:59.60 --> 0:17:29.170
Droege, Sam
And we have the strong curled hairs again, you know, you get into that without
seeing filthy. You get into the notion of is that are those long hairs or not.
You know, if you haven't seen any that gets a little bit tricky. So you can
look and discover life. You can look for several other characters. You can
always look mostly most of a lot of the literature is in discover life. You can
look at the descriptions. You can look at pictures and if you're super lucky.
0:17:29.270 --> 0:17:32.320
Droege, Sam
You can get to a collection to confirm some of these things.
0:17:34.300 --> 0:17:34.690
Droege, Sam
And.
0:17:35.500 --> 0:17:35.970
Droege, Sam
Yeah.
0:17:34.20 --> 0:17:41.620
Maffei, Clare J
Sam, that reminds me. I have pulling that up. We had some questions from last
last I was holding for Mike.
0:17:42.730 --> 0:17:51.450
Maffei, Clare J
But while you're right there, we we're having trouble with the malice terminating
in a long, stout spine. When we wrapped up last last.
0:17:52.300 --> 0:17:54.590
Droege, Sam
Right. So.
0:17:55.270 --> 0:18:5.670
Droege, Sam
Uh, actually, this is a term we're gonna turn this over to you, Mike, but the
malice which apparently is a four leg spine, that's as something I'm not very
familiar with. You wanna?
0:18:5.350 --> 0:18:33.420
Mike Arduser (Guest)
Yeah, yeah, it's basically this kind of generalized, but it's the antenna
cleaner. It's one the bees do this. There's, if you look at the mail is it's a
combination of several things. It's got a spine and it's got a lamella and it's
usually got a little groove in it. It's a pretty specialized piece of equipment
and it varies among these. Sometimes it's very reduced, sometimes it's got long.
0:18:38.140 --> 0:18:38.650
Droege, Sam
OK, I'm gonna.
0:18:33.510 --> 0:18:38.740
Mike Arduser (Guest)
Time and sometimes shorts. Fine, it varies, so it's sometimes useful and in.
0:18:39.280 --> 0:18:41.490
Droege, Sam
I'm going to try and locate it on filthy.
0:18:40.530 --> 0:18:42.730
Mike Arduser (Guest)
OK. It's yeah, it's.
0:18:49.100 --> 0:18:51.470
Droege, Sam
I guess I have to reverse this.
0:18:52.150 --> 0:18:52.800
Mike Arduser (Guest)
Yeah, I.
0:18:52.170 --> 0:18:54.600
Droege, Sam
To see because on the on the underside.
0:18:56.740 --> 0:18:57.100
Maffei, Clare J
Also.
0:18:56.700 --> 0:19:2.750
Mike Arduser (Guest)
Sometimes can be. It can be hard to see. Sometimes I I grant you that,
especially if the legs are folded.
0:19:4.600 --> 0:19:11.300
Maffei, Clare J
Law brings up just with the color thing. Wanted to note a way I think about as
black matte versus black iridescent.
0:19:12.230 --> 0:19:15.870
Maffei, Clare J
And then I think asking about the malice, does it function as a comb?
0:19:17.360 --> 0:19:21.430
Mike Arduser (Guest)
In a way, yeah, I mean it's it's, it's it's sometimes called the antenna
cleaner.
0:19:22.730 --> 0:19:23.950
Mike Arduser (Guest)
So if.
0:19:25.790 --> 0:19:26.430
Mike Arduser (Guest)
I mean, that's.
0:19:27.890 --> 0:19:29.520
Mike Arduser (Guest)
Yeah, if you watch bees.
0:19:30.260 --> 0:19:32.760
Mike Arduser (Guest)
In the field, sometimes they do. I'm kind of.
0:19:34.540 --> 0:19:48.50
Mike Arduser (Guest)
But they they use those front legs and they're they're working there antennae.
And I they're doing. They're using that antenna cleaner, that malice and the
velum. There's tooth structures, the malice is the spine part. The velum is the
lamella.
0:19:48.830 --> 0:19:50.260
Mike Arduser (Guest)
And they're the.
0:19:51.770 --> 0:19:52.520
Mike Arduser (Guest)
Or you're getting there.
0:19:54.420 --> 0:19:56.200
Mike Arduser (Guest)
Now, yeah, you're looking at it head on now.
0:19:56.980 --> 0:19:59.90
Droege, Sam
OK, let me try and I'll spin it to the.
0:20:7.480 --> 0:20:10.550
Mike Arduser (Guest)
Yeah, this this tells you that how difficult it can be to see it sometimes.
0:20:17.670 --> 0:20:18.780
Droege, Sam
Wait till we get to nomada.
0:20:25.490 --> 0:20:25.880
Droege, Sam
Alright.
0:20:25.540 --> 0:20:26.620
Mike Arduser (Guest)
That's it. That's it.
0:20:26.880 --> 0:20:27.350
Mike Arduser (Guest)
Uh.
0:20:29.250 --> 0:20:34.390
Mike Arduser (Guest)
So you see where it's coming out of the of the the the tip.
0:20:35.300 --> 0:20:37.230
Mike Arduser (Guest)
Of the tibia on the underside.
0:20:38.130 --> 0:20:38.810
Mike Arduser (Guest)
And.
0:20:40.300 --> 0:20:40.670
Mike Arduser (Guest)
So.
0:20:42.390 --> 0:20:49.400
Mike Arduser (Guest)
I just encourage you to I I think I'll be have that. I I can't imagine turning.
I don't don't.
0:20:50.80 --> 0:20:54.100
Mike Arduser (Guest)
Umm, but it varies, but it's always there and it's something worth looking at.
0:20:55.410 --> 0:20:57.560
Droege, Sam
OK, so this you're basically saying this is.
0:20:59.900 --> 0:21:4.260
Droege, Sam
More spine like and what's the alternative state which will look, try and look
for?
0:21:4.660 --> 0:21:10.840
Mike Arduser (Guest)
Uh. More reduced and it it's, you know, it's comparative until you see a
sample. You what's what's.
0:21:11.930 --> 0:21:14.30
Mike Arduser (Guest)
You know what's out? What's reduced what?
0:21:15.120 --> 0:21:15.470
Droege, Sam
OK.
0:21:16.670 --> 0:21:18.650
Droege, Sam
This is where we need to take more pictures.
0:21:22.440 --> 0:21:23.880
Droege, Sam
All right, so.
0:21:24.780 --> 0:21:28.390
Droege, Sam
That's good. And we can look at our next specimen.
0:21:34.850 --> 0:21:42.240
Droege, Sam
All these things which is I think we're gonna get be going to verga and antra
ventrus and.
0:21:41.440 --> 0:21:42.710
Mike Arduser (Guest)
OK. That's a good pair.
0:21:51.660 --> 0:21:51.900
Maffei, Clare J
Well.
0:21:43.80 --> 0:21:52.140
Droege, Sam
Yeah, here we get into actually something we haven't done much of, if any, is
looking at the abdomen and the pitting pattern.
0:21:52.610 --> 0:22:1.160
Maffei, Clare J
I I'm actually gonna introduce or introduce you. Wow, interrupt you because we
had two other questions that we had pinned for last class.
0:22:6.920 --> 0:22:7.180
Mike Arduser (Guest)
Yeah.
0:22:4.0 --> 0:22:17.240
Maffei, Clare J
I left a note rear coxa Karina. So we were talking about that and anterior
plural pitting in regards to pumla, but I didn't give myself more specific note
on so we probably scroll up to wherever that character was.
0:22:19.120 --> 0:22:19.340
Droege, Sam
Are.
0:22:19.170 --> 0:22:26.440
Mike Arduser (Guest)
Yeah, the the hind coxal Carina, which is diagnostic for the dicer tasmia
subgenus or group.
0:22:27.490 --> 0:22:29.960
Mike Arduser (Guest)
It's hard to often very, very hard to see.
0:22:30.660 --> 0:22:31.610
Mike Arduser (Guest)
And.
0:22:32.740 --> 0:22:35.510
Mike Arduser (Guest)
But as diagnostic and.
0:22:37.910 --> 0:22:49.800
Mike Arduser (Guest)
But it's one of those one of the I think one of the more difficult things to
see you know on pinned and dried specimens because you can't move it around but
it's present and not present on any other osmia group.
0:22:51.390 --> 0:22:55.730
Mike Arduser (Guest)
And it it it's once you see it, it's it's pretty evident, but it's just the
actual.
0:22:56.820 --> 0:23:0.400
Mike Arduser (Guest)
Ability to see it. Sometimes it's just very difficult. It's that's been my
experience.
0:23:1.600 --> 0:23:20.170
Droege, Sam
So Mike, when we were looking at it last time, we did have a specimen that was
supposed to have it. And our my impression of it was that it's less of a Corina
and more of a super sharp angle.
0:23:21.700 --> 0:23:22.120
Droege, Sam
Exactly.
0:23:24.240 --> 0:23:25.830
Droege, Sam
OK, good. And we'll.
0:23:19.960 --> 0:23:26.870
Mike Arduser (Guest)
Eric. OK. Yeah, that's a good way. Yeah. More of an edge. Sharp edge. Yeah.
Yeah. Good point. Good point.
0:23:26.750 --> 0:23:38.60
Droege, Sam
We we have here and atramentous, so why don't we just take a look and see if we
can see the not sharp edge of that and.
0:23:39.280 --> 0:23:39.740
Droege, Sam
Talk about.
0:23:41.30 --> 0:23:45.210
Maffei, Clare J
I also copy and pasted a picture. The screenshot from last time.
0:23:45.750 --> 0:23:46.30
Droege, Sam
Uh-huh.
0:23:46.330 --> 0:23:49.520
Maffei, Clare J
That we have taken of that specimen, it was some fasciata.
0:23:50.390 --> 0:23:55.720
Maffei, Clare J
So I don't. I don't know if, uh, Mike, you have easy access to the chat and
want to look at it, but that's.
0:23:56.520 --> 0:23:57.250
Maffei, Clare J
A contribution.
0:23:57.50 --> 0:23:57.450
Droege, Sam
Thank you.
0:24:1.110 --> 0:24:10.500
Droege, Sam
This is another one of those horrible places to look at a lot of times I think
we might be able to get in here though on this specimen.
0:24:14.910 --> 0:24:15.640
Droege, Sam
So.
0:24:26.770 --> 0:24:27.70
Mike Arduser (Guest)
Thanks.
0:24:27.150 --> 0:24:28.150
Mike Arduser (Guest)
No. Yeah, yeah.
0:24:19.370 --> 0:24:42.20
Droege, Sam
This, I believe is the coxa right here. Trochanters do I have that right, Mike?
And my little, yeah, yeah. And then the others, this is, I don't know why even
what these things are called, but they're recessed into the segment. And this
whole area here is just rounded over. And if you recall from that picture and
Claire has that picture.
0:24:43.760 --> 0:24:57.290
Droege, Sam
The the I guess I would call it the. I don't even know what the orientation
here would be, but the the flat face and then the side face. If we wanna call
it that.
0:24:58.550 --> 0:25:5.560
Droege, Sam
The junction was very very sharp, whereas in these others it just is sort of
rounded over.
0:25:7.380 --> 0:25:10.850
Droege, Sam
But you know, there's a lot of hairs. It's hard to see.
0:25:12.30 --> 0:25:13.720
Droege, Sam
I tend not to use it.
0:25:14.900 --> 0:25:15.410
Droege, Sam
For those.
0:25:14.670 --> 0:25:22.40
Mike Arduser (Guest)
There are other way. There are other ways to to determine if you've got
conjunctive or some fasciata. Other than that, coxal.
0:25:22.910 --> 0:25:23.330
Mike Arduser (Guest)
Angle.
0:25:27.30 --> 0:25:28.180
Mike Arduser (Guest)
Yep, Yep.
0:25:23.280 --> 0:25:38.460
Droege, Sam
But particularly, you know, conjunctiva has the nice two raised, little dim
pimples on its face. And so fasciata is a little more tricky. It vibes
differently like ohh, why is it? This is a little bit hairier but.
0:25:40.660 --> 0:25:42.970
Droege, Sam
Often it's a process of elimination.
0:25:44.210 --> 0:25:49.250
Droege, Sam
But we did see that. So that's something that we can keep in our.
0:25:50.560 --> 0:25:56.990
Droege, Sam
Mine to look for again when we get so fast. Yeah. Which is not a common bee.
But you know, I've seen it in urban areas even.
0:25:58.160 --> 0:26:0.240
Droege, Sam
What do you see it? Where do you see it out West.
0:26:0.630 --> 0:26:4.370
Mike Arduser (Guest)
Umm. If you get down South further, you know.
0:26:5.200 --> 0:26:12.520
Mike Arduser (Guest)
So Oklahoma, Texas and I mean it can be common there, but we only have a couple
records from Missouri. That's it.
0:26:18.580 --> 0:26:19.370
Droege, Sam
So this is.
0:26:16.150 --> 0:26:19.440
Maffei, Clare J
And some whoopee. Do you have up there or, Whoopi, are you going to do next?
0:26:20.50 --> 0:26:30.680
Droege, Sam
Yeah, this is atramentous. So we will take a a look here at the abdomen was
something we wanted. What was, how did we.
0:26:31.850 --> 0:26:35.350
Droege, Sam
Yeah, doesn't have. Well, we can look at the Koran, the.
0:26:35.850 --> 0:26:36.520
Mike Arduser (Guest)
The mandible.
0:26:41.990 --> 0:26:42.360
Mike Arduser (Guest)
Yeah.
0:26:36.190 --> 0:26:47.160
Droege, Sam
Let's look at the mandible. Would be the same as felty. Basically, might as
well look at it, because this is something that up over and over. And also
since I think we can see.
0:26:48.160 --> 0:26:50.980
Droege, Sam
Here the hypostome wall cavity.
0:26:51.800 --> 0:27:9.420
Droege, Sam
Umm, we can first of all, we can look. It's pale hairs like Mike was talking about
and they are not long and now I'm gonna spin it to the side. So you see that
better. So if you recall there was there was quite not super dense hairs but
they were long hairs there.
0:27:10.600 --> 0:27:14.90
Droege, Sam
Now I'm gonna move it so that we're looking at the side.
0:27:15.250 --> 0:27:22.200
Droege, Sam
It's from the side and hopefully we'll be able to picture the Carina a little
bit better around the hypostome wall cavity.
0:27:26.740 --> 0:27:34.390
Maffei, Clare J
We have clarification in the chat. Did you say asking after Ventress is common
in Oklahoma and Texas?
0:27:35.420 --> 0:27:37.390
Mike Arduser (Guest)
No. We were talking about sub fasciata.
0:27:42.430 --> 0:27:43.980
Mike Arduser (Guest)
Let's it.
0:27:40.70 --> 0:27:44.400
Droege, Sam
I don't know as Atramentous where it's dirt. All the common here.
0:27:45.40 --> 0:27:55.540
Mike Arduser (Guest)
Yeah, yeah. After Ventures is one of the most common osmia in the Midwest, but
I've never, I don't know that it gets all the way down to Texas. I have found
it in eastern Oklahoma and.
0:27:56.270 --> 0:28:5.170
Mike Arduser (Guest)
Arkansas, Louisiana, Iowa, Michigan it's it can be very common, but it may be a
complex of species, which I don't know if we'll talk about or not, but.
0:28:6.810 --> 0:28:13.680
Mike Arduser (Guest)
There's there's, there's. There's a lot of variation in atramentous throughout
in its whole range. This kind of suspicious.
0:28:14.770 --> 0:28:15.130
Mike Arduser (Guest)
And.
0:28:15.970 --> 0:28:17.360
Mike Arduser (Guest)
Just let it go with that for now.
0:28:19.590 --> 0:28:20.540
Droege, Sam
Yeah, this is the problem.
0:28:19.860 --> 0:28:23.690
Mike Arduser (Guest)
It's a. It's a. It's a very common species, visits all kinds of flowers.
0:28:25.10 --> 0:28:35.270
Mike Arduser (Guest)
Nest nest in natural cavities. Holes in wood, things like that. Very cheap, you
know, super common, really. Almost as common as home alone.
0:28:37.990 --> 0:28:38.760
Mike Arduser (Guest)
In the Midwest.
0:28:40.850 --> 0:28:43.270
Droege, Sam
Yeah. Same pretty much same pattern in the East.
0:28:51.120 --> 0:28:51.340
Droege, Sam
Yeah.
0:28:43.580 --> 0:28:52.850
Mike Arduser (Guest)
And it gets way up north as well. So and and his in his sympatric with Verga
and those two are very easy to confuse which will probably talk about.
0:29:5.340 --> 0:29:6.350
Mike Arduser (Guest)
Yeah, you can see that.
0:28:53.280 --> 0:29:25.430
Droege, Sam
Right, so this is a little bit it's a smaller bee, so it's not as prominent as
filthy. I've got it magnified as much as I can, but I think in a way you can
see here's the hypostome oral cavity is and here the tongue is gonna go
recessing it. This is the Corina and you can see first of all it's not very
tall in comparison to filthies and it's uniform. So here here's where it's
curving back under now we can't see it because of the mandible and the hairs.
0:29:25.990 --> 0:29:35.0
Droege, Sam
But there's no abrupt change anywhere in that fence, like Corina this whole
length. So.
0:29:36.10 --> 0:29:50.0
Droege, Sam
If you're doing a comparison with two B's and one has a lot of architecture in
here and the other doesn't, then you know they're different because they don't.
Really, you don't really see a lot of variation in that type of stomal.
0:29:50.680 --> 0:29:53.190
Droege, Sam
Cavity Corina pattern.
0:29:56.210 --> 0:30:21.40
Droege, Sam
At least I don't, and it could be a indicator. Ohh. I wonder if the other side
is a visible here too. Oh, look at that. So this is more straight on, but
here's this fence going around here and here it is on this other side. Slightly
oblique, so you can see the raise and you can see the lack of any elevational
change along there.
0:30:22.230 --> 0:30:29.580
Droege, Sam
It took me a while to feel comfortable looking at that because if you're not,
if not, someone's not showing you, then.
0:30:30.380 --> 0:30:33.370
Droege, Sam
Then you get. You start making up all kinds of stories. So.
0:30:34.350 --> 0:30:35.970
Droege, Sam
This is why we're doing this.
0:30:37.210 --> 0:30:43.20
Droege, Sam
Alright, so we can take a quick look at the mandible, maybe even in this
picture here.
0:30:43.980 --> 0:30:46.170
Droege, Sam
And see. Yeah, sure.
0:30:46.660 --> 0:31:0.30
Droege, Sam
Umm, these are really diverging corini or, yeah, these mandible lines here
going down and then you can see I'm on the other side just you know splaying
apart.
0:31:1.510 --> 0:31:2.460
Droege, Sam
Between the.
0:31:3.540 --> 0:31:4.190
Droege, Sam
Edges.
0:31:4.940 --> 0:31:6.60
Droege, Sam
And Umm.
0:31:8.210 --> 0:31:12.730
Droege, Sam
Here you can't quite see the shape of the mandible, but we'll we'll take a
quick.
0:31:13.550 --> 0:31:14.590
Droege, Sam
Gander at that.
0:31:31.840 --> 0:31:36.150
Droege, Sam
So you can see that diverging here, the corona almost goes all the way.
0:31:45.320 --> 0:31:45.590
Droege, Sam
Yeah.
0:31:44.60 --> 0:31:46.330
Mike Arduser (Guest)
Yeah, that's a good deal. On the opposite side, yeah.
0:31:46.460 --> 0:31:50.250
Droege, Sam
And there we have this, you know, pretty much rectangle shape here.
0:31:51.580 --> 0:31:51.850
Droege, Sam
Yeah.
0:31:53.400 --> 0:32:3.300
Droege, Sam
Something that's useful that I know out West Mali and Terry were working on for
Western species is are these distances distance from?
0:32:4.560 --> 0:32:22.920
Droege, Sam
This tooth to that tooth versus this tooth to that tooth. So in some species
like this one, you got quite a gap in other species compared to this one, this
gap and others, this middle tooth, at least the tips are about equidistant
between the two, and that can be useful.
0:32:24.530 --> 0:32:27.20
Droege, Sam
But in this particular case.
0:32:27.760 --> 0:32:30.680
Droege, Sam
What we're gonna look at next is the most, I think.
0:32:31.660 --> 0:32:43.770
Droege, Sam
Well, actually you had this picture. We're going to look at too. Maybe we
should. Well, let's look at the abdomen and then we'll look at your burger
picture and see if we can see what's in that picture.
0:32:53.600 --> 0:33:0.860
Droege, Sam
But not learned about these. Yeah, we got a lot of glare here. Not too
important. Let's see if I can change.
0:33:28.500 --> 0:33:30.940
Droege, Sam
Other whites here now.
0:33:31.600 --> 0:33:36.460
Droege, Sam
Appears to be that. Yeah, you're seeing actually. Here is the ring light right
there.
0:33:37.170 --> 0:33:38.520
Droege, Sam
So but.
0:33:38.60 --> 0:33:40.330
Maffei, Clare J
Yeah, if you did it, it was a, it's fine.
0:33:41.370 --> 0:33:53.960
Droege, Sam
OK. But what we're and it doesn't matter a whole lot cause it's the we can look
to either side of the center and not look don't look into the light. In fact
we'll move it off a little bit.
0:33:55.60 --> 0:33:56.970
Droege, Sam
So what we're looking at is.
0:33:58.310 --> 0:34:13.240
Droege, Sam
I think most of the time in osmia you don't get the pits all the way. Some get
really close, like one or two pit diameters. I think pumila for example. So
there's a gap here where no pitting is and then these pits start.
0:34:13.910 --> 0:34:22.210
Droege, Sam
Umm, but we're gonna look at Verga next and you'll see that this is more like a
6th or so of the segment. How do you describe it, Mike?
0:34:24.620 --> 0:34:35.900
Mike Arduser (Guest)
Well, it was pretty good. I mean, there's those ethical margins, I think of
apical margins are narrow and nature venturous and very narrow.
0:34:37.890 --> 0:34:52.880
Mike Arduser (Guest)
Comparatively, in some of the other species, they're more, well, they're more
explicitly defined, very sharply defined, and actor venturous are not. Not only
are they narrow, but they're not as sharply defined as in some others.
0:34:56.280 --> 0:35:8.60
Droege, Sam
Yep, and now our pear, which might also mentions in northern areas, often shows
up together, but I think a Virgo also has being a lover of ericaceous shrubs.
0:35:8.50 --> 0:35:9.480
Mike Arduser (Guest)
Totally, totally, yeah.
0:35:9.450 --> 0:35:12.780
Droege, Sam
Yeah. And let's see, here we go.
0:35:15.590 --> 0:35:17.0
Mike Arduser (Guest)
OK, that the.
0:35:13.500 --> 0:35:17.460
Droege, Sam
So, Mike, what are we looking at here? Maybe I'll see if I can pull it up.
0:35:18.340 --> 0:35:23.50
Mike Arduser (Guest)
This is the four leg of osmium verga.
0:35:24.150 --> 0:35:33.250
Mike Arduser (Guest)
And what I want you to notice this is the underside. So you're on the upper
photo, you're seeing the basic Tarsis and then the following tarsal segments.
0:35:34.120 --> 0:35:51.130
Mike Arduser (Guest)
And what I want you to focus on is the apex of the Bayesian Tarsis and the
following segment and notice how the CD or the spines are more stout well
developed than those more basil.
0:35:52.80 --> 0:35:52.590
Mike Arduser (Guest)
And.
0:35:54.230 --> 0:36:14.440
Mike Arduser (Guest)
And atramentous, they're all the same. They're not differentiated at all. But
in verga those apical spines or CD are definitely more stout and more
differentiated than the others. And that's even though this is an SEM shot,
obviously. But it's obvious under the light microscope as well.
0:36:15.50 --> 0:36:16.480
Droege, Sam
Right. Let's see if we can.
0:36:15.280 --> 0:36:40.190
Mike Arduser (Guest)
Ohh and whether and I think those are happy they have something to do with
pollen removal when they can. I can never see. Can't see that happening. Also
the four days of Tarsis, the length times the width is different in intravenous
and verga itself. But Basitar SIS is longer and verga and shorter in ventures.
But if you don't have them, you don't see both. It may be difficult to.
0:36:40.730 --> 0:36:44.360
Droege, Sam
Alright, let's see if we can pick this up here.
0:36:45.660 --> 0:36:58.130
Droege, Sam
Again, the problem is it's the inside edge of the front and at the legs are we
might be able to. This is also a small bee. Let's see what happens when we look
at this one from the side. So.
0:37:0.380 --> 0:37:2.710
Droege, Sam
We may have a hard time, but you know.
0:37:4.60 --> 0:37:6.550
Droege, Sam
I'm gonna put some white underneath here.
0:37:7.360 --> 0:37:9.30
Droege, Sam
See if that helps.
0:37:9.870 --> 0:37:11.320
Droege, Sam
Umm, sort of.
0:37:13.390 --> 0:37:23.60
Droege, Sam
Did this without wrecking the specimen, so I think you can more or less see
that all the hairs are.
0:37:24.660 --> 0:37:25.640
Droege, Sam
About the scene.
0:37:28.250 --> 0:37:34.60
Droege, Sam
But there's no fat hairs versus skinny hairs. All the hairs are the same
stoutness.
0:37:35.370 --> 0:37:36.660
Droege, Sam
Would you describe it that way, Mike?
0:37:37.50 --> 0:37:38.150
Mike Arduser (Guest)
Yeah, that's what it looks like.
0:37:39.60 --> 0:37:39.310
Droege, Sam
OK.
0:37:38.840 --> 0:37:41.610
Mike Arduser (Guest)
To me, yeah, I would. So that would be extra batteries.
0:37:42.180 --> 0:37:47.820
Droege, Sam
Yeah, right. So now let's grab a Virgo. We'll look at a couple of these other.
0:37:48.550 --> 0:37:49.400
Droege, Sam
Characters.
0:38:2.860 --> 0:38:3.140
Droege, Sam
Thank you.
0:38:9.170 --> 0:38:9.830
Droege, Sam
There it is.
0:38:28.630 --> 0:38:34.320
Mike Arduser (Guest)
Eastern Minnesota, as far as we know, there are no records West of there,
nothing from North Dakota.
0:38:36.170 --> 0:38:39.990
Mike Arduser (Guest)
And it's also in Ontario and other northern parts of Canada.
0:38:41.300 --> 0:38:41.970
Mike Arduser (Guest)
To call me.
0:38:49.350 --> 0:38:49.750
Mike Arduser (Guest)
Wow.
0:38:43.920 --> 0:38:51.340
Droege, Sam
Which is, you know, here we do get them. For example, coastal, plain and
Maryland, which is pretty far South.
0:38:52.410 --> 0:38:54.920
Droege, Sam
Again in these ericaceous.
0:38:56.450 --> 0:38:59.490
Droege, Sam
Pine oak, acid soil.
0:38:59.830 --> 0:39:0.60
Mike Arduser (Guest)
Yeah.
0:39:0.630 --> 0:39:3.960
Droege, Sam
Huckleberry, understory kinds of circumstances.
0:39:5.960 --> 0:39:22.430
Droege, Sam
I am, you know, in the past I've had a lot of Virgo specimens and gave most
away for the last round of whoever wanted them. And I have a specimen. Here it
is. I'm going to apologize in advance for it being very gluey.
0:39:24.760 --> 0:39:25.870
Droege, Sam
Right. So.
0:39:27.140 --> 0:39:28.500
Droege, Sam
Well, Sir, with the abdomen.
0:39:29.510 --> 0:39:33.460
Droege, Sam
Guess we'll take a look at the hypotonia cavity. Out of curiosity later, but.
0:39:35.900 --> 0:39:37.610
Droege, Sam
If we go.
0:39:38.660 --> 0:39:40.650
Droege, Sam
To the abdomen here.
0:39:44.270 --> 0:39:46.240
Droege, Sam
Ignoring the ring light.
0:39:47.270 --> 0:39:50.30
Droege, Sam
So green light is there at the center, but take a look at.
0:39:51.170 --> 0:39:52.380
Droege, Sam
Quite a difference.
0:39:53.540 --> 0:39:54.150
Droege, Sam
Andy.
0:39:55.610 --> 0:40:0.220
Droege, Sam
The amount of area that's unpitted you know, that's very.
0:40:1.350 --> 0:40:12.840
Droege, Sam
Very noticeable. That alone would tell you that it should be verga. Verga also
has a lot of black hairs on the clippies, but I don't think intravenous has any
on the Clippers. I could be wrong.
0:40:15.860 --> 0:40:17.970
Droege, Sam
Yeah. So.
0:40:18.740 --> 0:40:20.660
Droege, Sam
That's that's pretty good.
0:40:21.720 --> 0:40:22.960
Droege, Sam
It's a little bit bigger.
0:40:24.20 --> 0:40:24.340
Mike Arduser (Guest)
Yep.
0:40:24.240 --> 0:40:29.610
Droege, Sam
I'm not hugely bigger now. Let's see if we can find.
0:40:30.610 --> 0:40:33.710
Droege, Sam
In our non SEM world here.
0:40:35.60 --> 0:40:36.130
Droege, Sam
The.
0:40:37.30 --> 0:40:38.860
Droege, Sam
Umm, we might be.
0:40:39.980 --> 0:40:40.340
Droege, Sam
Well.
0:40:43.50 --> 0:40:47.410
Droege, Sam
Is that the front there? Let's see. Let's zoom in there and see what's going
on.
0:40:48.870 --> 0:40:51.340
Droege, Sam
Not 100%, they're not all glued together.
0:40:54.650 --> 0:40:57.410
Droege, Sam
Right. Well, while we're there yet.
0:40:58.240 --> 0:41:4.670
Droege, Sam
Not a great shot of the well. You can see the black hairs on the clipeus there
quite extensive.
0:41:5.620 --> 0:41:7.890
Droege, Sam
And let's move.
0:41:9.130 --> 0:41:9.880
Droege, Sam
Too much?
0:41:10.940 --> 0:41:14.130
Droege, Sam
Let's move to see if we can see.
0:41:16.870 --> 0:41:18.760
Droege, Sam
Some of the.
0:41:19.870 --> 0:41:24.280
Droege, Sam
Umm yeah, I'm I think we're gonna maybe not be able to see that.
0:41:25.40 --> 0:41:32.390
Droege, Sam
As the front, so look at all. There's a lot of glue here. This is a very bad
example of gluing.
0:41:33.730 --> 0:41:40.310
Droege, Sam
Normally we try to get it between the abdomen and the thorax in that general
area, but this is across the face.
0:41:41.860 --> 0:41:45.410
Droege, Sam
So much for production work, but so we're looking at the the.
0:41:46.750 --> 0:41:47.700
Droege, Sam
Yeah, from basil.
0:41:46.270 --> 0:41:47.770
Maffei, Clare J
Damn, you appear to have a pop up.
0:41:49.240 --> 0:41:52.510
Droege, Sam
No. Learn to IDE's. Ohh I should attend that.
0:42:0.960 --> 0:42:1.300
Mike Arduser (Guest)
Yeah.
0:41:53.640 --> 0:42:15.870
Droege, Sam
Umm, so I don't know that we can see it because we're looking at the outer face
rather than the interface. And so we're gonna say can't see it, but that was a
great SCM shot. You saw the Atria Ventress legs. I think it was pretty clear
that the hairs were the same size and we now have a.
0:42:16.640 --> 0:42:21.440
Droege, Sam
New character that I'll put in today into the guides for Virgo.
0:42:23.670 --> 0:42:29.440
Droege, Sam
Do you know any other species that have that, that spine thing going on?
0:42:30.500 --> 0:42:30.750
Droege, Sam
No.
0:42:29.810 --> 0:42:42.100
Mike Arduser (Guest)
No, I don't, Sam. But it for sure it's the only only species with the quadrate
mandibles and the diverging Corina that has it.
0:42:43.150 --> 0:42:43.720
Droege, Sam
Yeah.
0:42:43.40 --> 0:42:45.450
Mike Arduser (Guest)
With and without, with dark scope will have this so.
0:42:46.330 --> 0:42:56.520
Droege, Sam
I'm just wondering about it's ericaceous habits where other what other osmia
and I know other osmia go to blueberries and stuff.
0:43:2.410 --> 0:43:2.740
Mike Arduser (Guest)
Well.
0:42:57.360 --> 0:43:3.680
Droege, Sam
Umm do we have any other osmia that are have such a strong preference? I wonder
if it's something to do with that.
0:43:6.70 --> 0:43:6.430
Droege, Sam
OK.
0:43:4.100 --> 0:43:13.840
Mike Arduser (Guest)
Lattice UPS the records are two records are too few to be sure, but I've always
found it at vaccinium in up north but.
0:43:14.0 --> 0:43:18.720
Droege, Sam
And have you looked to see whether it has that? I'm just wondering about this,
whether that's fine.
0:43:17.810 --> 0:43:20.560
Mike Arduser (Guest)
No, it it it doesn't. Yeah.
0:43:20.690 --> 0:43:20.960
Droege, Sam
OK.
0:43:22.640 --> 0:43:51.930
Droege, Sam
All right, so we've got a couple of good characters for that tricky pair, and
now we're going back up to where we were before and going into a bunch of which
is here. So this is the group that we tackled and now we're into a whole series
of species, some of a bunch of which are not super common. Collinsii would for
me is the most common of that group.
0:43:52.490 --> 0:43:55.550
Droege, Sam
Umm, but like this apple in the area?
0:44:2.140 --> 0:44:3.280
Droege, Sam
OK so.
0:43:55.620 --> 0:44:11.210
Mike Arduser (Guest)
That's that's extremely northern. I don't even think there are any. I don't
think there's any US records of that. It's known from Ontario and close to the
border, but I don't think I've ever don't think there any records of it being
in the US It's a big dark black osmia.
0:44:12.240 --> 0:44:12.850
Droege, Sam
Mm-hmm.
0:44:12.40 --> 0:44:13.610
Mike Arduser (Guest)
It's pretty, pretty sizable.
0:44:14.800 --> 0:44:17.330
Droege, Sam
That's the kind of thing that should show up on.
0:44:22.70 --> 0:44:22.560
Mike Arduser (Guest)
I will.
0:44:18.540 --> 0:44:24.90
Droege, Sam
Royal what royal aisle? What is it? Not Front Royal Isle Royale.
0:44:24.730 --> 0:44:25.0
Droege, Sam
Yeah.
0:44:23.340 --> 0:44:26.770
Mike Arduser (Guest)
A royal? Yeah. I mean, it could well be. Yeah, yeah.
0:44:27.90 --> 0:44:28.460
Droege, Sam
You know, we'll have to go.
0:44:29.890 --> 0:44:37.670
Droege, Sam
So suesens, so that takes, we move away from that black one and we get to the
blue. So now.
0:44:38.790 --> 0:44:48.830
Droege, Sam
We're dealing with through lessons. Let me see if I have any right now. Again,
I gave away a bunch, but maybe talk a little bit about the interesting thing
about summer lessons.
0:44:49.360 --> 0:44:51.960
Mike Arduser (Guest)
Well, yeah, there are a couple. Uh.
0:44:53.420 --> 0:44:55.930
Mike Arduser (Guest)
I haven't. I have not collected that bee.
0:44:56.890 --> 0:45:6.420
Mike Arduser (Guest)
Ever in the Midwest, there are plenty of records, a hundreds of records from
certain places. Indiana and southern Michigan.
0:45:12.40 --> 0:45:16.620
Mike Arduser (Guest)
For a long time, I know I can't remember her name. Woman who did it.
0:45:17.760 --> 0:45:23.600
Mike Arduser (Guest)
Her graduate work in Cleveland few years ago, she found a lot of serial lessons
in clever.
0:45:23.550 --> 0:45:23.850
Droege, Sam
Mm-hmm.
0:45:25.120 --> 0:45:25.550
Mike Arduser (Guest)
Which?
0:45:25.250 --> 0:45:26.340
Droege, Sam
Oh yeah, that was.
0:45:27.620 --> 0:45:28.200
Droege, Sam
Uh.
0:45:29.790 --> 0:45:32.500
Droege, Sam
Cheese on why she does it in two weeks ago.
0:45:28.740 --> 0:45:33.660
Mike Arduser (Guest)
Yeah, you worked with her. She's she said. She said. She said she said Ohio
State.
0:45:34.730 --> 0:45:35.240
Droege, Sam
Yeah.
0:45:35.530 --> 0:45:42.280
Mike Arduser (Guest)
Yeah. So yeah, she found a bunch. So it's it's a weird bit shows up. I mean,
it's an introduced species, first of all.
0:45:43.370 --> 0:45:54.720
Mike Arduser (Guest)
And I'm not sure when it was introduced. It wasn't purposeful, but it's been
around. I I've seen specimens from the 1920s, so it's been around for a while,
but it seems real spotty, at least in my experience.
0:45:54.310 --> 0:45:57.620
Droege, Sam
Yeah, it was Melissa, Melissa Springs. Yeah.
0:45:56.910 --> 0:45:58.100
Mike Arduser (Guest)
Melissa spring. Yep. Yep.
0:45:58.810 --> 0:46:13.570
Droege, Sam
And so and then in Maryland, I have found in Maryland and West Virginia two or
three, I I'm gonna say and then but again similar to what Mike was talking
about.
0:46:14.600 --> 0:46:28.400
Droege, Sam
This introduced species, so I guess it's pretty confirmed has been here a long
time and it was all over the place. It was all over Washington DC and these
areas that I collect very heavily and I've never seen.
0:46:29.220 --> 0:46:29.450
Mike Arduser (Guest)
Huh.
0:46:30.650 --> 0:46:30.910
Mike Arduser (Guest)
Well.
0:46:31.740 --> 0:46:32.30
Mike Arduser (Guest)
Ah.
0:46:29.500 --> 0:46:36.670
Droege, Sam
11 either so something something shifted, it's still around and seems like as
you go further north.
0:46:37.590 --> 0:46:41.290
Droege, Sam
I think Ontario has regular records and stuff like that, but.
0:46:41.160 --> 0:46:41.390
Mike Arduser (Guest)
OK.
0:46:43.890 --> 0:46:46.880
Droege, Sam
All right, so ID wise.
0:46:48.0 --> 0:46:57.590
Droege, Sam
It has a a couple slightly different feels to it because it's not. It's not
from this hemisphere.
0:46:58.430 --> 0:47:11.490
Droege, Sam
Like this where it says proposal triangle predominantly shiny. That's that
stands out. These two pairs of hair Tufts is different than the single pair of
tear Tufts that are there.
0:47:12.200 --> 0:47:15.610
Droege, Sam
And it's just looks a little different.
0:47:17.230 --> 0:47:19.570
Droege, Sam
At and otherwise you have to have a key it out.
0:47:34.330 --> 0:47:34.650
Mike Arduser (Guest)
Huh.
0:47:20.230 --> 0:47:37.380
Droege, Sam
I'm going to look and see if I said Simillima here either. Yeah, that one's
gone. So my which is, is sad because Simillima does show up. We don't get it in
Maryland, but if you're in New England and I assume.
0:47:40.440 --> 0:47:40.720
Mike Arduser (Guest)
Yep.
0:47:38.500 --> 0:47:42.240
Droege, Sam
Throughout the upper Midwest, you can see that that species.
0:47:43.740 --> 0:47:44.190
Droege, Sam
Uh.
0:47:43.190 --> 0:47:45.160
Mike Arduser (Guest)
That's fairly common in the Great Lakes region.
0:47:46.510 --> 0:47:50.400
Mike Arduser (Guest)
And uh, down to northern half of Iowa.
0:47:58.280 --> 0:47:58.480
Droege, Sam
Yep.
0:47:51.780 --> 0:47:59.640
Mike Arduser (Guest)
We only have one record from Missouri, so it doesn't get very far South in the
Midwest. It's like you said, Upper Midwest and and north of that in Canada.
0:48:3.620 --> 0:48:3.880
Mike Arduser (Guest)
It's.
0:48:5.850 --> 0:48:6.920
Mike Arduser (Guest)
Ohh yeah, that's.
0:48:1.350 --> 0:48:15.540
Droege, Sam
Yeah, and it's too bad we don't have one because this you need to to get a feel
for what this this character here looks like this four Bayes Itarsi, which has
all kinds of things going on, it's.
0:48:16.710 --> 0:48:35.100
Droege, Sam
Very. It's relatively short. It's kind of flattened and broad and it's got some
curly hairs on it, but it's one of those things that's, you know, you, you it's
it's better if you can see it. I don't know of any good pictures of it, but
it's a.
0:48:36.800 --> 0:48:43.660
Droege, Sam
Distinctive when you see it, but a lot of times you are trying to make it into
that when you don't see it.
0:48:45.150 --> 0:48:48.350
Mike Arduser (Guest)
And it's a fairly good size B compared to some of the others.
0:48:48.970 --> 0:48:49.170
Droege, Sam
Yeah.
0:48:51.150 --> 0:48:51.900
Droege, Sam
Yes.
0:49:3.120 --> 0:49:3.380
Mike Arduser (Guest)
Yeah.
0:48:54.960 --> 0:49:4.430
Droege, Sam
OK. So and then that, that character here, this four basestars is I think it's
the only one that has that across all the species.
0:49:5.160 --> 0:49:5.620
Droege, Sam
And I'm.
0:49:4.740 --> 0:49:5.630
Mike Arduser (Guest)
I think so, yeah.
0:49:7.550 --> 0:49:12.270
Droege, Sam
OK. And then we move on Charsadda, another one of these.
0:49:16.90 --> 0:49:16.420
Mike Arduser (Guest)
Yeah.
0:49:12.510 --> 0:49:18.990
Droege, Sam
I'm far northern species. So you wanna ohh here? We get into name changes.
0:49:20.100 --> 0:49:22.330
Droege, Sam
So you wanna talk about that one a little bit, yeah.
0:49:21.280 --> 0:49:28.500
Mike Arduser (Guest)
Yeah, tarse in Mitchell. He referred to Tarceva as Integra.
0:49:29.300 --> 0:49:38.430
Mike Arduser (Guest)
Umm. And integrity is a valid species, but it's western and that the time I
don't think he knew about the presence of these others, but.
0:49:39.280 --> 0:49:41.90
Mike Arduser (Guest)
Then it was called Kenoyer eye.
0:49:51.650 --> 0:50:8.660
Mike Arduser (Guest)
So Torcedores current name. It's a big, big, osmia beautiful big osmia in the
north sand pretty much a sand obligate nest in the ground in sand, which is
pretty unusual for most of our eastern species, and attaches its cells to the
roots of grasses.
0:50:9.840 --> 0:50:23.600
Mike Arduser (Guest)
It likes ericaceous plants, but does go to other things. I've seen it buzz
pollinate roses. So it's once you get into northern part like the P and
Ontario. It's in sandy areas. It can be common.
0:50:24.780 --> 0:50:26.180
Mike Arduser (Guest)
But it's a very dramatically.
0:50:27.410 --> 0:50:28.230
Mike Arduser (Guest)
Attractive.
0:50:29.360 --> 0:50:31.920
Droege, Sam
Yeah, I've got a a male, but that's it.
0:50:32.90 --> 0:50:32.840
Mike Arduser (Guest)
Ohh OK.
0:50:33.990 --> 0:50:37.380
Droege, Sam
From I think that work we did with the National Park Service up on.
0:50:41.390 --> 0:50:41.780
Mike Arduser (Guest)
No.
0:50:38.40 --> 0:50:43.310
Droege, Sam
Umm the edge of Lake Superior on maybe picture rocks or something?
0:50:43.110 --> 0:50:49.110
Mike Arduser (Guest)
Yep, yeah, that's where the Grand Sable dunes. That's where that bee is. Very.
That's why I first found it.
0:50:50.430 --> 0:50:50.880
Droege, Sam
Yep.
0:50:51.190 --> 0:50:53.330
Mike Arduser (Guest)
It's still up there. OK, I'll see.
0:50:54.780 --> 0:51:2.710
Droege, Sam
Right. So sadly, we can't go through a lot of those week. We now are back down
to.
0:51:3.310 --> 0:51:5.800
Droege, Sam
Uh. Differences.
0:51:6.880 --> 0:51:12.600
Droege, Sam
Here which are getting into subtle mandible differences. You wanna talk about
that, Mike?
0:51:22.780 --> 0:51:23.10
Droege, Sam
Yeah.
0:51:17.990 --> 0:51:23.190
Mike Arduser (Guest)
Yes. And we and we kind of covered it a little bit at the at the outset, but.
0:51:23.870 --> 0:51:27.80
Mike Arduser (Guest)
Again, something mandible, Osman mandibles and the female.
0:51:27.400 --> 0:51:27.910
Mike Arduser (Guest)
Umm.
0:51:28.570 --> 0:51:39.590
Mike Arduser (Guest)
Ohh range from just square like things to gradually becoming pinched or reduced
mediately or submit.
0:51:50.110 --> 0:51:52.400
Mike Arduser (Guest)
And then the apical tooth.
0:52:10.580 --> 0:52:10.750
Droege, Sam
Right.
0:52:6.170 --> 0:52:10.950
Mike Arduser (Guest)
Uh, collinsii and Proxima are very similar. Colombia's bigger.
0:52:11.710 --> 0:52:23.490
Mike Arduser (Guest)
But they barely overlap in range, at least in the Midwest, Proximus Northern,
and they overlap a little bit, but not very much, at least over here. And but
they're easy to confuse.
0:52:25.150 --> 0:52:26.70
Mike Arduser (Guest)
Where they do overlap.
0:52:25.450 --> 0:52:36.0
Maffei, Clare J
We have a question from the chat. Laurel's wondering if Osmia usually buzz
pollinate. Do they mostly visit plants in the air? Cashier Solan HCA families.
0:52:37.310 --> 0:52:57.520
Mike Arduser (Guest)
They've visited a lot of different things, you know, but I the only one I've
ever seen or heard a Buzz, Powell Mading is Tarceva, and it was on Rose Roses,
which roses get buzz pollinate a lot by bumblebees and some other things. But
I've never heard or seen any other eastern Osmia Baz pollinating.
0:52:58.280 --> 0:53:16.510
Mike Arduser (Guest)
But you know they like. There's there's a couple penstemon specialists and they
do visit and there's the georgica, which you probably talked about last week,
is asked her acne specialist. So it's not just the ericaceous stuff, but that's
in the north. That's a very important group of plans for us.
0:53:18.580 --> 0:53:19.860
Mike Arduser (Guest)
I don't know if that made any sense.
0:53:21.880 --> 0:53:23.50
Maffei, Clare J
Sounds good to me. Thanks.
0:53:24.600 --> 0:53:24.830
Mike Arduser (Guest)
What?
0:53:24.310 --> 0:53:33.620
Droege, Sam
So we're looking at a clinciu here and I have to tell you, Mike, that I had
some specimens from Northwestern Pennsylvania.
0:53:34.60 --> 0:53:34.430
Mike Arduser (Guest)
Uh-huh.
0:53:34.300 --> 0:53:46.580
Droege, Sam
Umm that I was like this could be Proxima and I spent a lot of time trying to
using your key and other keys and I just could not make up my mind it was just.
0:53:47.400 --> 0:53:52.30
Droege, Sam
Difficult to see first why I didn't have any Proxima material around so.
0:53:54.650 --> 0:53:54.910
Mike Arduser (Guest)
What?
0:53:53.540 --> 0:53:56.70
Droege, Sam
I never did resolve that Dundrum.
0:54:1.30 --> 0:54:1.470
Droege, Sam
Umm.
0:54:8.910 --> 0:54:9.150
Droege, Sam
Your.
0:54:20.790 --> 0:54:47.190
Droege, Sam
That also just for people this you can see that this this rim here. Here's one.
Here's T2. This rim is a little bit wider than atramentous too. So every once
in a while when I'm plowing through lots of adventurous, I'll catch a ohh wait
a minute. This one has a a little bit of a wider unpitted band and then it will
turn out to be flimsier.
0:54:49.800 --> 0:55:3.510
Droege, Sam
If I'm just using characters other than, say, some of the mandible ones and
things like that, the gallium, I'd like to see if we can see that here. You had
mentioned here in the keys that.
0:55:5.10 --> 0:55:10.800
Droege, Sam
That guilia hairs longer brown and here gaily hair short, pale.
0:55:15.280 --> 0:55:15.570
Mike Arduser (Guest)
Yeah.
0:55:17.680 --> 0:55:18.480
Mike Arduser (Guest)
Yep, Yep.
0:55:11.910 --> 0:55:30.140
Droege, Sam
But you know what is your long and what is your in your short is a problem and
if you don't have any materials and then brown versus black sometimes it's
like, ooh, is that brown, brown or is that tan pale? You know what I mean?
0:55:31.140 --> 0:55:31.430
Droege, Sam
So.
0:55:29.660 --> 0:55:32.40
Mike Arduser (Guest)
Yeah, yeah, yeah, I know. Yeah, yeah.
0:55:32.140 --> 0:55:33.0
Droege, Sam
This is.
0:55:33.970 --> 0:55:39.330
Droege, Sam
Yeah, I would. I would love for more, more characters on that pair.
0:55:40.60 --> 0:55:40.700
Droege, Sam
At some.
0:55:41.780 --> 0:55:42.720
Droege, Sam
Future point?
0:55:44.490 --> 0:55:51.200
Droege, Sam
There, but I don't know if we can even see the Galia where here? Because the
tongue not extended.
0:55:56.470 --> 0:55:56.790
Mike Arduser (Guest)
I don't.
0:55:56.130 --> 0:55:56.900
Droege, Sam
There are.
0:55:58.230 --> 0:56:1.760
Droege, Sam
There are reasons that the old time.
0:56:2.650 --> 0:56:15.120
Droege, Sam
Uh, professionals like Mike, not that you're old, Mike, but who you know, do
things like pull the tongue and spread the mandibles and pull the genitalia
bar.
0:56:16.130 --> 0:56:21.840
Droege, Sam
Really useful to see some of these other characters, or at least easily see
them.
0:56:22.530 --> 0:56:23.640
Droege, Sam
Alright so.
0:56:27.250 --> 0:56:40.200
Droege, Sam
I am guessing so here. We're looking at the tongue. We can actually sneak a
look at the hypostome wall cavity here too. But in the Carina. So I am going to
assume.
0:56:40.880 --> 0:56:41.540
Droege, Sam
That.
0:56:42.710 --> 0:56:48.800
Droege, Sam
So the Galia are these outer sheathing like things and that these are the hairs
you're talking about?
0:56:48.680 --> 0:56:50.710
Mike Arduser (Guest)
Yeah, uh short tail hairs.
0:56:51.550 --> 0:56:53.530
Droege, Sam
So long.
0:56:54.530 --> 0:56:57.850
Droege, Sam
Would be 2 times that three times.
0:56:59.520 --> 0:56:59.880
Droege, Sam
OK.
0:56:56.720 --> 0:57:0.720
Mike Arduser (Guest)
Yeah, at least, yeah. At least two times. Yeah, maybe 3. Some of them.
0:57:1.570 --> 0:57:1.810
Mike Arduser (Guest)
Yeah.
0:57:1.670 --> 0:57:6.940
Droege, Sam
All right. So that's that's good to know. Alright. Anyway, this has been my own
struggle.
0:57:8.380 --> 0:57:10.190
Droege, Sam
I know some of the.
0:57:17.740 --> 0:57:19.460
Mike Arduser (Guest)
Ohk OK, OK.
0:57:11.250 --> 0:57:41.680
Droege, Sam
It was because it was right at the edge of the range, like it could be. It was,
it was. These were canopy traps which weird things show up in canopy traps, so
like. Ohh, could that be, you know, looking at the notion that weird things
show up there, could that be a actually be Proxima? But never in the end I
think I called it both. So here hypostomus cavity. Here's your corina edge.
This is straight on. So you can't see anything.
0:58:1.380 --> 0:58:1.790
Mike Arduser (Guest)
Trigger.
0:58:6.530 --> 0:58:18.460
Droege, Sam
So again, it's always pays to if you can take a looky look. If you're trying to
differentiate a couple different species and see if this shape.
0:58:33.920 --> 0:58:40.810
Droege, Sam
Well, we get into a bunch of unknowns and also northern things. Maybe we could
talk about that next time and then we'll get it to males.
0:58:57.800 --> 0:58:58.10
Mike Arduser (Guest)
Yeah.
0:58:57.110 --> 0:59:3.670
Droege, Sam
Might. And then we're in even more uncharted territory. Unless Mike whips out a
male guide between now and then.
0:59:4.890 --> 0:59:6.120
Mike Arduser (Guest)
Well, I do have.
0:59:14.630 --> 0:59:14.900
Droege, Sam
Mm-hmm.
0:59:7.230 --> 0:59:16.710
Mike Arduser (Guest)
One, it's it's not. Doesn't include some of the extreme northern things or
extreme southern, but I'll send it to you and see you think.
0:59:18.100 --> 0:59:18.420
Maffei, Clare J
Cool.
0:59:17.210 --> 0:59:18.570
Droege, Sam
OK. Thanks Mike.
0:59:18.20 --> 0:59:26.350
Mike Arduser (Guest)
And I can also I can also send you specimens if let's talk later. If there's
some things you need mails, and I've maybe I've got time to send them so.
0:59:25.910 --> 0:59:27.130
Droege, Sam
Yeah. No, I would love that.
0:59:27.980 --> 0:59:32.10
Droege, Sam
And then I can score them for discover, life, things and whatnot too.
0:59:32.670 --> 0:59:33.40
Mike Arduser (Guest)
OK.
0:59:33.430 --> 0:59:34.50
Droege, Sam
And send them back.
0:59:34.460 --> 0:59:37.600
Mike Arduser (Guest)
OK. Alright. Thanks. Thanks Claire.
