Thanks, Claire.
Alright, I'm gonna shift to share and we're continuing.
So, Mike, our news, there's not here.
Neither is Rob Jean, who are sort of the heavyweights in terms of looking at andrina subgenera.
So I'll plow through Mike's key and most of it's pretty straightforward.
Straightforward.
It's always good to have their insights, particularly since they're the mic's the developer, but they can't make it for a variety of reasons today and let me finish the share thing here and we will flip back and forth between resources online and we can use the microscope 2.

Droege, Sam 0:46
Two, so last time we stopped at whole endrina and if we go back, we're really talking basically one species.
So if we look at Holland, Drina here in the Discover Life mail Andrina key, we have to work on our alphabetical miss.
I guess it's more than one one species, but there's andrina.
Cressoni is the one in the east that really.
Yeah.
Is this species that people come into contact with?
There are several others here.
On those are Western, and I'm unfamiliar with them, so we're really going to focus on, you know, the aspects of endrina cressoni.
And let me show it's very distinctive.
It's the kind of thing that in the mail is gives itself away almost right away by just looking at it.
So we'll go to a picture here.
So here's a picture, and it's the face that's really the distinctive part in the mail and the female.
It's trickier, and we spoke about that last time here.
You're looking at a incredibly wide head for an endrina, and you have a completely yellow clipeus these little spots here are often in in andrina species, males.
And so we're, we're ignoring them.
And then there are the periocular areas.
So these are the areas outside of the clipeus which is running like that that are also yellow.
So, but the tricky thing is, and I think maybe we mentioned this last time, one out of two hundred 250 or so aren't not going to look like this big chunks of the yellow are missing and replaced with usually a something that would be called maybe a brownish cast to the integument.
And in the I have not seen this, I don't believe, but I think Mike was mentioning maybe Rob was that in a few cases there could be nothing there.
So all the yellow is gone, but usually you have indications that something is up.
In other words, it's not all black integument and, but just to let people know this can erode quite a bit away, and often in a patchily, patchy kind of approach.
And it's still that species.
So there's a strong within Mikes key here.
Let's go back.
We're working in an area here with whole andrina, so these are all males that have a strong pronotal collar and also have yellow on the clippies at least some yellow on the clipeus.
And we worked our way down to here and specifically Mike has here listed in contrast to the previous one, which was very simple to submarginal cells and versus 3 submarginal cells.
So the two were that pair andrina group, which are Willow specialists and small.
And then three sub marginals, which is basically the most common aspect to andrina, but one has to be aware that andronic and many other bee species can drop a submarginal boundary line.
So it looks like they're too, but if you look at the opposite wing, a lot of times you'll see that it is 3 there.
So I'm going to sneeze, I think, and I'm gonna turn away now.
If I say that I never sneeze, so anyway, back to.
The sub general.
So that's whole endrina and what we're seeing is tourguides densely.
And this is a characteristic in the females in particular.
That's useful.
Very densely pitted throughout the entire tergite, so it's not different from the impressed area or the base area.
And then you have periocular maculae present.
So we also have several other Members.
So apparently this holds true for them also.
So these are the areas to the side of the clipeus and they when they talk about macule here, that's the fancy term for they have yellow markings of some kind.
And those markings are large and and usually occupying a good chunk of that pair ocular area and so excuse them in skew, skew them with scattered but obvious pits even at low magnification.
Not sure how that plays in.
It's not something I look at when I'm addressing whether I have andrina Chris Onii or not.
Again, like with bird watching some species just you just know without having to look at the field guide.
Again, this is one of them, so the the contrast is that your tergites have weak or weekly punctate at most, and we'll give that green and usually without pictures.
So in punctate is again a fancy word for there are no pits visible, and then the periocular maculae.
So the yellow markings to the side of the clipeus are usually absent, and you're.
Yeah.
And really present so often in these other groups here when they are present there small restricted dots of yellow and a lot of times usually right on the the the suture between the clipeus and the periocular area and usually.
People overlook them.
But you know specifically they have to be addressed because they would be a marking in the pair ocular area, but they're restricted and small and usually they're not there at all.
And the here it's a scutum is usually completely unpitted so that brings us to these final two again both with strong.
Ohh strong I put a little angles to their own Odom and also yellow clippies areas.
And so here we're separating 21 is super common layer endrina that's basically andrina Miserables and not not andrina you can.
I also read that as not endrina, but it's I think.
Note andrina.
Perhaps so here.
This is mostly more are they Midwestern species and not an eastern species, and this other one is quite common everywhere.
Let's take a quick look at the at Distributionally where these things show up, or at least the species.
So node endrina I think are mostly specialists.
I know the one is on A roadside plant that the squirty, although Jack Neff notes that a lot of times he doesn't, you know, he sees tons of the.
The onion related or the Scordia eye and does not get this endrina species on it.
There's some question there and this andrina tried Questura is primarily Texas and a little bit more to the West of there, but not a lot.

VICTOR DEMASI joined the meeting

Droege, Sam 8:21
It's really relatively restricted, but now found in Arkansas, so should be looked for this North Korea or North security has also shown up here.
Look to see if the distributions show, but you can see mostly primarily Midwestern, but there's now records here in the southeast and is probably, you know, another group of andrina that are overlooked quite a bit.
So trying to get back to the guide here.
Here we go and go to the bottom.
So that's the note endrina group and then the other one is the gosh, what was the name of that layer endrina, which will be Miserables, I believe entirely.
And I can.
Yeah, layer andrina.
There's the box has only one marked, so that should be our friend, Miss Robles and Umm.
So we'll go back to the guide and we'll look at the some pictures of Miserables, the other species.
I don't have photos up at this point in discover life, so here in the mails, yeah.

Maffei, Clare J 9:38
Because it's simpler question.
With the not andrina or not andrina umm with the females I made a note that said you said that this group has a different kind of look, like a big head, some kind of different kind of architecture.
True for the males also?
Or is that a female kind of vibe?

Droege, Sam 10:01
Yeah, I don't have any in the collection and it's not something that I've run into.
I'm in the mail, so I've run into it in a in a female and I didn't know what I was looking at at the time, partially because it was in Tennessee and we are Georgia and was like way out of range.
So I can't answer that.
Umm, uh, when you look at the character here, Gina, posterior margin carinate.
So that's the cheek and what it's saying is there's a raise line around the edges, very similar in a way.
Again, I don't have a picture, but would be similar in a way to the species that are on the Switzer group of the cornice, so those would be the shrubby dogwoods of different kind and they all have this Corina that's raised area that that it in different ways borders the cheek.
Let's see if we can find a picture of that.
This is pretty distinctive.
Again, I don't have.
Sadly, I don't have the species, but we can look at a corona lining the cheek here.
Ohh in the guides and let's you know.
Out of curiosity, let's look and see if there is any picture and discover life under node endrina put there by someone else.
I really have to learn spelling and there we go.

Maffei, Clare J 11:29
There.

Droege, Sam 11:33
And.

Maffei, Clare J 11:33
You have another scordi mail in Flickr, but I'm not sure if we can see the Gena well.

Droege, Sam 11:42
OK.
Oh, you mean that?
Umm, we have taken a picture of 1.

Maffei, Clare J 11:48
Umm it's on Flickr.

Droege, Sam 11:49
No. Amazing.
OK, let's go into there and go to.
Open up a new flicker window.
And.
You would have a series, but that's not always the case.
Is it North Korea has no how do we spell that he comes spilling it all right now are.

Maffei, Clare J 12:21
I know TH OS.

Droege, Sam 12:29
I think I have to start over with this thing NOTHORSCORDI correct.
Uh.
Ohh, maybe not a R after that.

Maffei, Clare J 12:44
Oh, I was muted and trying to tell you things.
Yeah.
Uh no.
Are NOTHOS CORDIC?

Droege, Sam 12:50
There we go.
Oh, here.
OK.
Yeah, we may have the the very picture.
I didn't realize it, so here we have.
Although oddly, I thought these were supposed to have much reduced pair ocular macule, and I believe Mike identified this, so I'm not quite sure what's going on there that's in the key.
So two beds?
Mikes not here, but indeed.
Look at that Corina here.
So Corina equals raised line, Gina equals cheek and you can see this thickened area that goes right along there.
And that's a pretty, umm, unique combination.
They also talked about the back, which I think we do have a back shop here being largely.
Umm Unpitted and I still see some pits in there.
Interestingly, so I wonder.
Yeah, you might have to revisit both that specimen and or the key here because so if we go back down to the proper place we're talking about tergites 1/4 weekly pitted.
I'm using in punctate periocular macular, usually absent, rarely present and large.
Ohh well, it says rarely present and large, so I guess that can compasses what we just saw skew them usually, although apparently not always unpitted.
Now if we look at note andrina, which we just were Gina posterior margin carinate check very dramatically show and all the way up to behind and touching the eye.
Uh periocular areas yellow, at least in part.
OK, we can go with that rear species.
I don't know where I got that.
There was no pitting on the back, just reduced.
OK, so that seems like a relatively straightforward species to identify with those characters.
Now if we look at the next one, so this is gonna be our very common andrina Miserables, which may be more than one species according to several people.
Sort of inspections of specimens, including ours.
So here the cheek does not have that margin.
And is not carinate.
In other words, there's not gotta raise line around it.
It's just normal cheek.
The pair ocular is dark without maculate.
OK.
So I think I overemphasized that these maculae were tiny and this group and that is not the case as we can, Dan going back here, those are substantial enough and it's also pretty wide like Chris Onii but reduce pitting on the abdomens.
Let's see if we can see that.
Umm.
Yeah.
So the you can see the pitting here on the abdomen in this upper part quite widely spaced, several pit diameters apart, whereas in prisoner eye they are basically lying on top of each other.
So let's now Andrina Miserables, which should have specimens lined up here.
Get out of prison Island and back to album.
And back to album list.
These are all in the collection section of UH.
Oops, I went too far.
Perhaps umm of.
Uh view my collections of.
Clicker our flicker account and you can make your own with I believe species.
Why did I click on the slides elsewhere and your own collection?
Stephen Falk showed me how to do that from Britain.
So now we're going to go to Endrina Miserables.
There we go and there is a fee.
A male right on deck.
So yellow black pair ocular outside of the clipeus and look at some of the other characteristics here.
If we can find the side, we should see no raised line.
I'm not sure we need to look at that because no raise line is what we mostly see in entering a species and the opposite character is the one we were just looking at.
And so that's pretty much it in the female.
This has a very polished central area in the mail.
Whenever there's a yellow clipeus involved, it's also very difficult to see what's going on in terms of pit and pitting inside that yellow area.
So it's usually not described.
Uh, but this sort of combination in the east of spring, species yellow with strong.
We'll ridges is often going to be Miserables and there's A and discover life.
You can key it through the whole system and come out with what that species might be.
I'm not sure.
Ohh I can tell you I believe this is true in the mails as well.
Let's see if we can find a back photo of this.
That's the abdomen.
Umm, where is it?
The thorax.

Maffei, Clare J 18:42
I yeah.

Droege, Sam 18:43
We yeah, go ahead.

Maffei, Clare J 18:43
What are you?
What are you looking at?
Cause I was gonna say that.
Umm, there's a bit in Discovery life.
I put it in the chat from Joel extracted from Joel Gardners material that says that the male has.
Where did it go?
Both sexes have a have a prenatal angle and Ridge, which is usually weak in the female but strong in the male, and I don't think we've talked about that dimorphism before.

Droege, Sam 19:07
Yep.
Yeah.
So, and that's that's a generality too.
So if there's a weak pronotal collar or Ridge in the female, it's.
Usually quite strong and often dramatically so in the mail.
So in general, that's that's sort of how all the endrina run.
This is actually a thorax.
One of our early shots were like, let's take apart a specimen and you can though see.
So this is where the head attachment was, and this is the now exposed pronotal collar.
Normally the head is covering this section and you can see an indication of this sharp corners to the Pro Nodo collar and a Cliff on the other side, which you can't see.
But tell me indication that that probably does have a strong pronotal Ridge and then back here the scutellum, although not perhaps the best of shots, because there's some a little bit of of flicks of of of goo from the specimen preparation and it tends to be very shiny and that is a good indication of Andrina Miserables when I'm.
I've got a question about it in the males and the females and see if that's going to show on the side, there's the front.
Ohh, here's here's our promoter collar without the head.
What we should keep this shot somewhere.
So here again, this is where the head was attached this whole area.
So the Pro nodosum and the pronotal collar, so the pronotum the collar, which is mostly what we see because we kind of see it when we look down from above and the head though is obscuring actually a quite large feature here.
So this all is a pro, I would umm, there's the pro node or lobes over there and the pronome then expands out to the sides and run this down.
But most of that's hidden by the head.
And when we talk about pronotal ridges and collars and angles and that kind of thing.
So here you can see is the the angle like mousers so it's pulled away again.
It's always best to see this under the microscope, but you're seeing this rounded area.
Is umm ah is.
Uh, what's the best way to describe it as a pulled away from the Skydome area?
And is creating some form of angle down the sides and if you did not, if you weren't, if you did not have a sharp paranodal collar angle situation, this would just curve right down.
You wouldn't see these earlike lobes there.
It'd be just straight down.
I'm not sure I'm now illumining anything that way or not.
And there's the female.
And we're looking at females here, but this central shiny area and the scutellum is a really unusual feature within endrina to have something where you have the scutum obscured by tessellations and ridges and fingerprinting and whatever you wanna call it.
And then this is all very shiny, very much error like in its presentation.
So a good indication of a endrina Miserables.
OK, so let's go back to the guide.
So we've left this area.
Now if you look you see it says 2.
So this section now is referring to still with a pronotal or prototype with these dorsal mental Ridge or angle present.
So it has that, but what it doesn't have is the Clippy is is not yellow or ivory.
The clip is is dark, so there are is no manipulations and then that in Mikes key here throws us right into till endrina which brings up some issues.
So let's let's go there.
Let's go to the discover life E, which I jumped out of there for a second and we will go back, go back down to the bottom where we can look at some general groups now under the basically the last several decades approach to subgenera till endrina would include and working on my spelling here St the the, the he there it is a fair number of species eastern ones including urethra glass stir.
Or plexa Romande and such.
But as we've mentioned several times, there's been these molecular people messing around with this traditional system.
So for example, reflexa in the old school way was Atilla Andrina.
But if you click on it now, it's listed as Melongena which has, umm, makes a little bit of sense.
The one of the characteristics of Mel Andrina in general is that the ocelli are set way back from the edge of the head and in perplexed, that's also the case.
There's the aselli and the the headroom is there.
It's about two or more Acela diameters, which is quite large and perplexed.
Has a species.
Is also quite large, so you know we have to always swing with what the changes are.
Right now, we're sticking with the old andrino subgenera in terms of keying, because that's what people know and the.
Ah, people haven't looked at all the different andrina species at the level to which you would want to be able to ascribe subgenera and look at divisions of subgenera.
But, umm, there's gonna be a bunch of changes.
So we're, I think within the guidebook now rename that the old this one here, the old subgenera system.
And and we'll start creating a a new one that's more up to date, but it'll be partial for quite a while anyway till andrina.
Includes.
Bring that list back up here.
It's already up.
Let me just refresh it in this way and a list of a lot of these are relatively large species.
The ones that are in the east that I'm familiar with, again, some matching with Mel Andrina and I'm not sure all of these.
Let's look at Areth or Gaster.
Went to melongena.
It also went to Melongena, so perhaps the whole thing is disappeared and but we're going with the old guide.
So the old guide would have separated out them from malandrino by the fact that melodrama has largely has a smooth pronotal collar and till andrina at least that perplexed a has a sharp, primal ridges on on its on its collar and several other things too that differentiate it from the other species of Malandrino.
So here we look at what mikes written about the traditional till andrina group pronotum with dorsal ventral Ridge crossed or terminated by a deep sulcus.
So I doubt we have that and it's gonna be a difficult thing to.
To show I think, although maybe we can if there's time we can dial back, I can try and pull a specimen and see if we can see this.
So you have a Ridge down the pronotum.
This is the dorsal ventral Ridge, and that Ridge.
Can in most PCs is, if they're present, are gonna is gonna be unbroken.
So it's just a Ridge.
So now imagine that you have a Ridge, and then in the middle of that you slice into it.
Often at at, you know blue angle and create a valley.
So that's sulcus is usually a valley, like a narrow channel that's sunken of on something.
So in this case they refer to it as a deep narrow sulcus.
Basically, slicing through that dorsal ventral Ridge, breaking it up into more than 1/2 parts, and then the alternative is that there is none, so that self is not there and not terminated deeply.
So this group has that combination of characters and the next group does not so.

Maffei, Clare J 28:38
So we do have a good picture of that characteristic on the endrina perplexity discover life page.

Droege, Sam 28:46
Let's take a look no.

Maffei, Clare J 28:46
It's.
Yeah, it's it's of the female, but it's the same thing that's happening.
So we can see what it looks like.

Droege, Sam 28:53
It may not be as prominent, so just in terms of perplexity, which is the one that in the east most prominently comes up.
They also have the No David has here.
They label process is is usually bidentate.
From this view, it doesn't look particularly bidentate, but below there are two.
Let's see if we can dive in there.
So if you angled it a little bit differently, you'd see that there's a large indentation.
This is a good notion, though, that you have to play around with the these pictures often.
Oops, that is too much.
Umm.
And these specimens to see whether it's bidentate or not.
And sometimes you can't, and so you should not use that character.
I'm going back to perplex a pictures.
So so here's males and females from the different picture.
Have right?
This is from Laurence Packer.
You can see also big cheek huge long mandibles in that particular species, and I'm not sure that.
So we're in the area, discover life is showing its limitations in terms of the size of the picture that we can see.
Really it's this is a problem both in photography and also a problem in umm ohm in in real life, like that's an area that's hard to see into because you're between over here would be the size.
So that's me zeppy sternum.
And then here's the head, and that head can be cocked different ways.
But if we use our imagination, here's the pronotal Ridge running down.
And this is the through the sulcus crossing it through there not a great shot, but you're getting an idea of place and activity.
You can see the richness there, even though Lawrence is shot is not super Duper high def.
Let's see, maybe there's something else in here, but that by deep chick, big huge mandibles and pronotal collar usually leads you right to.
Perplexed when you're working on it, I guess I looked through a lot of these things.
Let's just click on perplex again.

Maffei, Clare J 31:32
Yeah, if you scroll to the bottom, I go to perplexed and scroll to the bottom of the thumbnails.
The one on the bottom left just under that cheek.

Droege, Sam 31:44
No, umm.

Maffei, Clare J 31:44
One, there you go so female, but still feature down.

Droege, Sam 31:48
This no.
Furthermore, Oh yeah, we may have that.
Who did that?
Didn't we do that or to the other lab?

Maffei, Clare J 31:56
Yeah, that was.

Droege, Sam 31:58
OK, so I don't.
So here is the head and here is the Ridge and I'm not sure that the.
Uh, so it says distinct pronotal angle and Ridge and suture.
So the suture to me is not super visible.
It might be there going through the Ridge, but you can at least see the Ridge at this point behind the head.
Let's see if we have another.
Who's amazing number of pictures and discover life sometimes.
So here's the head again.
There's the angle where you can't see the Ridge any longer.
Here is just the the head and I believe that the pronotum is not umm uh.
Yeah, can't.
Can't quite tell what's going on there.
OK, so we may have reached the angle if there's time I can, I can jump up and pull a specimen of the perplexing and see if we can see that.
But that's like everyone, we have problems seeing the pro node or angle and the Pro nodal color and then you add.
Ohh, there also is a sulcus slicing through that they gets tricky, so maybe we'll come back to that because that is a useful thing to try and see.
But.
So, umm, maybe.
Let's see.
We have time.
Me. Go try and find out.
Specimen cause I've got the camera all set up.

Maffei, Clare J 33:44
Sounds good.

Droege, Sam 34:04
Right there.
I've got my.
OK, great.
We have specimens andrina perplexed.
Flip to the microscope pier and it.
Sure that it is on it is and let's take a quick look under the other microscope to see that we have.
Something visible.
Here.
Proof.
We try a different one.
Pretty good.
More time here and I probably will just knock your head off.

Maffei, Clare J 35:26
Probably have enough of them to do that.

Droege, Sam 35:29
Yep, always a little reluctant, but we'll sacrifice.
The.
Head wants to stay on is a problem here up.
Head is gone.
Great.
That's loaded up onto the deck.
And down the magnification, something that could be seen.
Initially, there's the side you're seeing a specimen without a head.
Bring the magnification up.
It's bunch of slightly goopy hairs.
Alright.
And this more centrally and then.
He's a little bit more power in here.
All right, this is reasonable.
We kind of saw this in that other photo, but if we look now, this is the skewed them running through here, you have the.
This is all part of the pro node on the head is is gone here and this angle right here would be the ohm pronotal Ridge slash.
Collar area and it's clearly separated from the.
Umm backside of the the specimen.
So it's not a smooth rounded over here.
There's a lot going on, and here's the sulcus running through the Ridge would be going down like this, but the sulcus divides it and the sulcus is presenting itself here as a series of of pits within the side of the specimen.
So it's not the kind of thing that I normally use, so I'm normally not keen things out using subgeneric guides and as we saw, there is also some changes going on.
I'm looking though for this year, this year, like structure that's indicating that there's a Ridge or that's some kind of Ridge.
And I'm not trying to determine whether there is a sulcus there or not because it it is often hidden by the head and is more difficult.
So, but that's that's what they're talking about there.

Maffei, Clare J 38:52
Thanks.

Droege, Sam 38:53
So if we move on beyond that, so the opposite, no pair of the character is dorsoventral Ridge of the prune item entire.
So in other words, ah, there is no dorsal ventral Ridge.
Ohh no, there's no sulcas.
There is the Ridge, so it's it's presented.
It's not smooth, which we're gonna get to way down in 17, I think.
And and it's not crossed by a deep, narrow sulcus.
So when we go there, then we'll go to the next one.
And basically what we're doing is we're looking at a group that has usually very prominent teeth.
This is which are not prominent in the females at the base of the mandible and or measurable malar space present.
So normally, like in discover life, we lump all the males that have these large basal teeth together and which there are six.
And then we step through them because there's a series of different aspects mostly having to do with hair color and antenna length that help separate them out with a little bit of work.
It's not too difficult, but if we go back to discover life guide and we see what the species are involved and why Mike put in that caveat about the length.
Oops, I went really want to restart the guide here be.
Uh, not just the basal tooth, but the length of the maller space.
Most andrina have minute maller spaces, so when you get into something that's.
Noticeable.
So they're never long.
They're not like bumblebee ones or ohh some of the other things there or collides, but some are noticeable.
Let's call them.
OK, let me focus andrina senses strict to would be the subgenus in this particular case.
So let's just limit it for my sake to the eastern ones.
So here I can click on east of the Mississippi and we have a easier to deal with things.
So Carolina, that's a good example of something that doesn't have how strong Gazal angle on the tooth at the base, a tooth tooth like thing.
Uh, yeah, but has a really long face.
So this is largely thought to be a blueberry specialist, so a lot of blueberry specialist types of bees have really long phases because they have to stick their face way down into those long corollas.
Those bell shaped corollas of that most of the of the vaccinations have, but not all.
Interestingly, and so Cornelli has the tooth frigida, does that have a tooth?
I can't remember and, but most of these have teeth on them, and in fact I think all the rest maybe not fast BI, but again, those Carolina fast.
I have this distinct Mailer space.
Umm, which again is not greater than the width of the base of the mandible.
So in bumblebees and collides, we're often looking at some specimens that have a malar space or the malar space is the distance from the eye to the mandible.
And that is greater in its length than the width of the mandible.
That's never the case in andrina, so usually we're talking something that's about, you know, a really large one would be about 1/5 of the of the width of the mandible in terms of its distance to the mandible from the eye.
So that now or length small but for andrina significant, most of these are the teethed ones and we would key those out in the on 8A separate complaint.
Umm.
Let's see.
Does that show up here?
Umm, I don't see it right now.
Uh, we could simplify this though, and see that would be under head cheek, Karina, free apical margin.
Clipeus should be under mandible clipeus all alphabetical should be helpful to me.
There it is.
Formation at base.
So there's the one with the distinct basal tooth.
So that's what the teeth and they can see.
There's one with a picture associated with it.
I think you're Dina crumbling and so there's this long angle down there.
And here's the similar picture.
And then somewhere we have the species involved, which are right here.
So this group shows up pretty regularly.
They all have teeth.
It's not all the endrina senses.
Strictu species in the east, but we go through and walk you through how to tell those six apart, which are easy to ID based on the tooth presence.
And so if we go back to Mikes key here again, so that's the endrina group.
So now when we look at the contrasting part of the couplet, it says the mandible is does not have a tooth or an angle and without a measurable malar space.
So it's basically the mandibles kissing right up against the base of the compound eye.
And there is no tooth.
So when we do that, we get into the till endrina.
Let's just bring up those species.
So we can take a look at them should restart this, go to the bottom.

And actually, Sam, I think maybe unless you can wrap up if you think Hillary is not gonna take too long, we should start wrapping.

Droege, Sam 45:22
Ohh OK, that's a good point.
Let's just look at till Andrina as a teaser for next time.
Thank you Claire for keeping me on track.
Ohh my gosh andrina argentiere is one of the most common bees in the east in terms of total captures, but you have to be near its host plant which is spring beauties and in the woods unbelievable numbers can occur until of course the evil lesser celandine which is a renowned jealous from Europe, comes in and wipes all of that community out.
A sad story that will end on apparently.
Are there any questions?

Maffei, Clare J 46:07
It's not.
We had a really small group today and then it's been quiet.

Droege, Sam 46:13
OK, they're the best students.

Maffei, Clare J 46:14
So I think that guess so I.
Yes, I think next week umm, it sounds like we will hopefully have mic back but not uh Rob for a couple more.
Yeah, he might not actually make it back until andrina's done.
So I'm not sure what we wanna do that.
We'll talk about it offline.
It's.

Droege, Sam 46:40
OK.

Maffei, Clare J 46:42
Yeah.
Any other questions with a couple of you that are on here and you got open mic for a couple minutes.

Droege, Sam 46:53
I'll I'll put this out because I'm working on the group.
The paper that Claire and I and others are working on on macropus and so looking for macropus ciliata.
Uh floral records.
So does anyone collected macrophilia?
It's an uncommon bee, but maybe someone here has, and if so, what species of plants did you collect them on?

Beiriger,Robert L left the meeting

Maffei, Clare J 47:29
We got nothing.

Droege, Sam 47:29
This, unfortunately, is generally the case where there's not not a lot of people collecting.

Maffei, Clare J 47:29
But thank you. Yep.

Mary Jo Mosby (Guest) left the meeting

Maffei, Clare J 47:35
Yeah.
And having collected it.

Droege, Sam 47:39
We OK all right.

Maffei, Clare J 47:41
OK.
I'll let those wonderful muses.

Matt Carlson left the meeting

Droege, Sam 47:44
Onto the next video video chat.

Maffei, Clare J 47:47
We'll do the next one so much computer today.

Droege, Sam 47:50
OK.
Thank you, Claire.
