Droege, Sam 0:03
I don't think I have any announcements except for yay, we're back.
You have any span.
I do not, no.
We have. Do we have anyone in lined up for a future talk at this point with states or not not so far. OK. I keep reaching out.
But people are busy, so I think it's. I think it's you and I for right now got it.
Do we have also maybe what's coming?
I haven't talked to you.
I don't think about this, but what?
Yeah. What are we gonna do after track and Trina? We'll finish track andrina today.
Let's chat about that after all, right?
And people, if people please put in the chat or e-mail me if you have requests, great. I think working through the subgenera is really helpful because that's how we went through with Mike in the beginning and he gave us some good notes on subgener as we went so.
I think that's a nice way to organize it.
But if the group has other ideas, you know if this is a resource for you. So let us know what you need.
Got it. Sam's turn now, right?
So we have been working through track and reading and we have been using a combination of the Discover life.
Pictures and Claire, you might pull up some pictures too. 'cause. Sometimes they're gonna be better.
And the microscope. I have a collection of track andrina females here.
And just as a side note, I have yet to really tackle the mail track adrina which I found confusing in terms of their ID string much more than the females, but that's in the future, particularly because we're getting some molecular.
Action and today our new molecular biologist volunteer though, came in and is setting up his shop.
So we'll get back to people on that in terms of what they want us to track down in terms of identification related morphology issues on species and we can.
Take volunteer.
Donations of specimens that are questionable, and we'll see what we can come up with.
OK.
So I'm gonna share.
We'll start with Andrea Quintillas.
We're gonna use the track Andrina Excel file.
Let me find where we are here and hit share.
Tuck my way through this screen.
And.
We should be good.
Can you see Claire?
Do you see the? No, it's great, all right.
So quintilis.
So the thing about Quintillus is that I almost never. I'm not even sure if we have any in our database.
See this species.
It's a Midwestern in terms of the distribution, so it's kissing up to the eastern United States and therefore our guides just a little bit.
And we'll go through the identification. I have material here from another collection, so we can.
See examples of this, but I have less of a internal portrait, so to speak, of what's going on here.
So when we when using the spreadsheet.
Sorry for zooming around here.
What we're looking for in terms of an initial investigation of a specimen that we have a feeling might be a certain species, is to go to that species, in this case quintilis, and then you.
Pace over until tab over until you find.
Sections that are in yellow highlighted in yellow and those.
In combination together should be a unique set of. If present characters, states of characters that would yield an identification for that species. So in this case.
We see when we're looking at the internal property of triangle.
So what's going on inside that property of triangle? You can see in most of the other species, you basically have just a long set of rectangles in terms of the cell structure.
In between the striations or the qurani that are raised up, usually very prominently within, but there are a few and these turn out to be, this turns out to be a useful character for separating them out.
Which are in this case not rectangular.
So Quintiles and Reni, the next species will be another one.
So quintiles.
Is has that and then we're going to pace through here.
Has big distinct bands of bright white here.
On T2 and three and what else do we got that note, mostly Midwestern.
And then under special features, the pitting all across T2 is uniformly dense.
So a lot of times pits almost touching so many times we see that there might be dense pitting on in T2 on the base but not on the rim, not or not near where the repressed area borders.
The base area, so as you recall there is a recessed area 2T2 and to T32.
But we really look at that that is in the track and Reena Group much further towards the base, sometimes almost 90% of the way to the base in comparison to other species of andrina.
So let's see what we can see.
Let's first go take a look.
And we'll in some of the remaining specimens, we'll take a look and see.
What the alternative is the rectangular 1, so this is the not rectangular view.
Let's jump over to the.
Camera and let me make it think that's the right combination.
Make it full. More here.
Take it down and there's my finger.
And here we go.
Gonna move the specimens so that it's.
Triangle area is maximized and we'll zoom in here.
Leave it at that for now, and most of you are triangle experts now.
So you can see that the portal triangle is using from this suture line, where we have the sutelum, the metanodum, the podium Podio triangle.
Is this usually?
Well demarcated triangular area that is dorsal or on top of the specimen and then.
The you have lateral faces and rear faces to the propodium.
And this triangle usually is, is crisply differentiated from the lateral sides.
So you can really see the triangular shape and the tip of the triangle is bends over onto this rear face, sometimes sharply, sometimes gradually.
And it's a little bit hard to see anything in clear for just a dirty dirty old specimen, probably 100 years old.
I'll zoom in a bit here and then.
Within. So that's a something to note, because many of the track and Trina have a very clear here's the boundary roughly here that this surface area is quite different from this surface area. And here it's not so much. In fact just seeing the properties triangle line or.
Border between the two is really tough.
Additionally, you'll see that these aren't long triangles.
These are more squarish or erratic.
Their shape we can look at another specimen too, so that's one.
But would you take that home?
To your mother and.
Ask if that's definitive, and then base your entire life savings on it. Probably not.
So here is T2.
So this is where the other two characters that help define the species. First of all, we'll see here.
On T2, you know what?
I'm gonna bend this specimen over a little bit more so T2 is more.
Horizontal to our view.
And.
That's pretty good right there.
Almost always and B specimen of their abdomen droops over under normal pinning conditions.
And that's useful because then you can see features on the front of the abdomen and the rear face of the primordial PUR podium.
What if you, if you had moved this abdomen up?
But sometimes people do simply by after pinning is holding the specimen or pinning the specimen upside down in clay. Or sometimes you can do that in.
Tome of a collection box and then it will dry like that again. You go run into this issue a lot of times.
There's some really nice features that would then be hidden because the abdomen is tucked too far up towards the thorax.
So here are the two features that were also mentioned that in conjunction with the.
Non rectangular look to the properial triangle.
You have very strong white boundaries.
Border hair trim is not complete, so it's not going all the way across.
And then you have a very, very dense pitting.
So basically those are touching or nearly touching throughout.
So here we see about 50% of the way up maybe.
Yeah, about 50%, I'd say is.
This line, which is representing the difference, the border, the boundary between the repressed area and the elevated area, and by those two terms we're talking very subtle differences.
These are existing. Basically all bee species, but usually it's followed the rim.
So this is pushed way back.
Another nice character of.
Back in dream.
So those are the main characters there are. If you go back here, one thing to do in a lot of cases, if you look still a little bit unsure is to go through some of these other characteristics.
So fat to thin ratio is 2, which isn't very much, right?
And comparison, you have three to four threes and three-point fives and threes sprinkled quite.
A bit around here.
Which means that simply that the thin area is not as thin and the fat area is not as fat in comparison to other species.
We'll take a quick look at that and you can see, you know sometimes.
When you're unsure territory, looking at the other characters, even if they're not highlighted, is useful in feeling better.
About your identification.
Feeling better about an alternative?
Identification. So let's just jump back here to the microscope and we will take a quick look at.
The face and see if it's possible.
Foveas are sometimes difficult to see.
And that seems to be well, we can make an outline up here, so not as broad.
So there's the that's a central there's a lateral.
Terrible specimen.
There's the facial phobia, not you know, eating up tons of real estate. And down here, hidden by the hares as usual, would be the thin area of that facial fovea.
We can see it kind of peeking out here.
I'm not gonna spend a lot of time on this because we've seen these several times, but there's an implication in just that small window that's relatively broad, not a slot as it is in some other cases.
So.
We'll remove that specimen of the what?
What do you do?
Yeah. So you kinda just address this like there's on the discover life species page. There's a little summary as there sometimes they are.
Yep, that point out, it points out the.
Has a. There's sometimes separate trees called too much, but.
Short term ethical areas you said that.
High vertex and in your in your CHEAT SHEET we do have a comment that says the thick pairs.
In this, in this summary, it's called the scale, like thoracic pairs. So if you want to show us those.
So it says scale like hairs scale like like hairs on the throat.
Yeah, on the thorax. OK. Do I mention that on here? You do on the special features in discover life. OK, well, you say here on your special on under special features.
Note that thickened hairs on speech Helena mosquito.
Yeah, so I OK.
This is probably the problem with having.
These very handy files is that they get replicated and my replication probably does not.
Well, it certainly doesn't have it. Like, I don't see it here, OK.
So we're looking on the thorax.
Well, first of all, let's go back here.
Let's take a quick look again just to get a visual.
So you just see in the Portal Triangle area which is this boundary.
Here you can see the difference, but this internal area is not really, it's sort of.
A. A little bit of a crazy mix of elevated striations making cells, but a lot of times they're curved or.
Occurs into them, so it's not a set of rectangles.
Here I think is what.
Is being mentioned already.
We're just looking at it from a matter of convenience, but these hairs are relatively thick compared to.
The normal hairs and I I'm we don't quite have the power here, but I believe you can see in here.
Indications that this thickness comes from minute to minute, perhaps scale, like sometimes things like this are called smaller hairs that are coming off the main stem.
So instead of having a nice thin line, you have.
A.
You certainly have that raka set thin line there and then it feathers out a little bit.
And that presents.
A more of.
A.
Densely thicker.
Specimen. So another andrina that has this. It's always very useful is andrina alleghenian sys.
There's a couple others too, I believe.
So yeah, so this now you're looking straight down on a lot of these, but you can see that here.
Here's a The your basic hair that is either got only a few side branches or hardly any, and then here are the sticker hairs that we're seeing.
To decide.
Alright, good.
I'm glad you brought that up there, 'cause. That was not in my obviously older version and we're looking straight down now.
Go all the way up and you can see in some of these the. So we're looking straight down these hairs over here and you can see these little side hairs or at least indications that they might be there at the resolution of this microscope. And then just a.
It's a strong contrast between these up here, these nice thin, normal hairs which do have.
Tiny little side here, but nowhere near this density, making it not so fat a thing.
And then there was a what?
Comment that the vertex is fairly tall, so that I think you have that covered in here by your the marking and the thing of the yeah, the.
I'm marking on the.
Excel spreadsheet.
Yeah, yeah.
So we can see usually things are measured here in diameters of. So you've got one, Asli, so you can fit at least one almost two, but it's certainly 1 1/2, certainly much greater than one, and I believe not looking at the spreadsheet myself right now that.
Many other track andrina these.
Celli are closer to the rim.
So there you go. If you're in the Far East, though, meaning over here near the coast, you I never see this, but I don't know the distribution completely.
But if you're in the Midwest, this is something that will pop up, OK?
Now we get to the very interesting case of Andrina Rennie and similar to Alleghen.
Y yes, is there anything else like should we be concerned about that?
They're best friends.
Well, you know, I'm not gonna get into their interpersonal relationships, but I believe they're in completely separate subgenera.
Oh yeah, it's a scrapbook. Never mind.
Yep. But, but if you look at so.
Allegheny Insurance and its cousin Atlantica, have.
The one of the features that track Andrina does have, which is they have.
A Corina that clips the tip of the property triangle right at the Edge where the property podium bends over to the vertical face.
And they have that too.
They have a very, very sparse.
Podio Triangle so who knows in the next of whatever number of revisions we're up against, that they make it lumped into the track injury unit or vice versa.
So now the situation that we're gonna look at is with Andrina Rennie and.
Looking at this particular specimen here.
And it's a longer story, which we don't have time right now, but if you have chestnut or Chincha Pen which is in the same genus in your region, you should look for the species a lot of times in a fresher specimen you can see potentially a little bit.
Of glint this it's got.
Fairly obvious blue glintings to the surface coloration of the integument.
You can see that.
Maybe a little bit if you're.
Ambitious in your look, but on old specimens, integument color often fades away.
OK.
So it's a. It turns out that it's a chestnut specialist, which is kind of cool.
And we had long for quite a while, thought it was one of these missing species that had been collected 100 years ago, and then we're not around.
And the answer was yes, it's still around.
Probably a lot less, but because it's a chestnut specialist.
Have to look on chestnut or Chincha Pen and almost nobody does, and until recently, a lot of people did not even think that of chestnut has a I'm looking for my tracking here.
Well, here's a different version.
And I'm going to go back.
As they didn't think of chestnut as even being insect pollinated.
Turns out it's complicated.
It is both wind likely to be wind and insect pollinated and it has its own little.
Specials, which is this one.
So let's look at the yellow.
Cells here first.
So first of all, we see that the.
The second antenna segment is quite long, so a lot of the others are basically squares or even less.
And that alone is going to take you to the bank if you're very good at your internal segment measurements in terms of separating it from the other species. It also vertex height is pretty tall.
1.5 to two, so similar to what we were seeing, which is almost exactly what we have for Quintiles, we also have.
A same thing.
Tall Corina, large cells, not rectangular. We don't have that here, as we'll see.
At least not as prominent that we were looking at.
And.
That here we go, pitting on T1 is very widely spaced.
So again, very different from Quintiles .5 to one we have two to four. So two to four pit diameters, in part on averaging on the 1st segment.
And here's some notes shell facul.
Ty others lab room may be broader than others.
So it sounds like more like notes to myself.
OK.
Let's take a look at our specimen and we'll start with the base here.
So what?
We're looking for is a fairly well. We can look for that shallow facial phobia.
Looking for the high vertex.
And we're gonna look at F2.
On the antennae.
So we'll let's do the antennae first, because that's the most distinctive.
Thing.
Is it F2 or F1?
Let me go back and check.
Yes, 2.
Yeah. So 1.25 to 1.4 so longer.
All right, so.
We look here again, we get into that situation that maybe in comparison. So here's.
F1 we're at high magnification 2 and this is F2.
I'm gonna bump the light up here.
A little more of an idea about this feature.
Where the heck?
There we go.
So.
See, we go.
To here. OK, that's pretty good.
We go back.
Has moved out of focus again.
So here's the lower boundary.
Here's the upper boundary. This would be the length and this would be. You know, you'd probably pick and believe there's measurement guidelines the maximum width.
So it is a bit longer, but not outrageously.
Off of the one to one configuration in that view. But let's take a look at the other.
Segment another one which might offer.
That's why holding it in your hand is helpful.
Because you can angle things back and forth, and none of these things are exact.
OK, pedestal F1F2 here. The length lengthiness that is this axis is greater than that axis is a lot clearer.
So there's a positive feature.
I'm gonna go back down.
In my light level.
Let's go to 100.
There's a note that these facial phobia are shallower may not show up well here.
But I think there's this. You can get a sense. It's not. They're not crisp and they're not deeply, partially because they're not deeply indented compared to the others.
Now the vertex I'm going to change the angle a bit so that we're as as in all these kinds of measurements, if you are not looking.
With the thing to be measured at exactly.
Angles in terms of the plane of the specimen. Then you're going to shorten it.
So here we can see.
There's the aselli.
That's our measuring tool.
So you can imagine one plus quite a bit. Plus nearing 2 there.
In terms of the vertex height and if we go back 'cause I need to go back.
And refresh on that 1.5 to two so that fits definitely in there in the vertex height.
Now, what was the other feature we we looked at those two, the non Oh well, we haven't yet but we'll look at that nonrectangular cells and being on T1 is sparser than most, OK.
So let's go back down.
Change.
Here.
Look at.
T1.
Get a view visual on that.
It should be good enough.
So we're not looking at T2 now, we're looking at T1, the first turgite.
So named and we should see pitting as we always do.
And.
Think that's probably sufficient.
I could boost the light up, but that takes just a little bit of time here to see that that is not like what we saw. For example in quintillas and some of the other specimens and including species including species, we're gonna about ready to show ragosa you can.
See that these pits are well spaced.
OK.
I think it's just a little bit dark here.
I'll just.
I'll just bend the specimen.
That's probably the easiest thing to do here, and that probably brings us into a better view of the podium.
Yeah, some glare, but I think.
On a closer inspection, so.
Depending on your frame of reference, you could say well, those are pretty close, but compared to many of the other.
Track and drinas in particular.
Which the pits, as we'll see again today are are basically right on top of each other.
There's quite a bit of space, in particular, if you use a pit diameter as a measurement.
Yeah, there we go.
So you can see very clearly that.
Now we have the propodium right next to us, so we will look at the triangle area here and we should see what are not clear rectangles.
So this is part of the.
You need a lot of experience over many, many specimens to say, well, I don't always have is that or isn't it?
But it's.
You can't really make rectangles out of that.
So if you have looked at many of these, that would be a good character. If you've not looked at many, you might have questions in your mind.
But again, we have this this area here is a little bit denser in terms of its I'll and surface structure.
There's the edge which you can barely make out of the properties triangle, but.
Not a very clearly differentiated.
A rectangular space.
So that is.
The chestnut bead.
Now we will go to Ragosa, which has tends to be a very a relatively common species.
I associate a very strongly with Woodlands.
And.
A pretty clean specimen, very strongly bowed just in terms of thinking about it.
Very strongly bowed.
Wanna use a different specimen?
Very strongly bowed facial phobia that leaves a large gap. There we go.
Between the side of the eye and the furthest distance of that skinny part of that facial fovea.
Let's go to our friend.
The sales spreadsheet.
So here's where it goes up.
This one, unlike the other two, are relatively common.
And so we look for our yellow areas here.
So we see scudam pitting .5 to overlapping, so it should be incredibly dense.
In fact, Mughosa probably is in reference to ruggedness or the amount. The extra amount of surface sculpturing this species would have, and I would tend to agree with that.
OK. Then we can look at the.
Long rectangles.
Then the not rectangular thing on the property of triangle keeping going, you see that T2 the depressed area.
Pretty wide .7 to nearly .9.
And do we have anything else I had do you?
Do you have something there?
Did I erase it on mine? Clare?
Special features.
Right. Also from our you know handy note within the CG page, I think you just said this one thing.
A circuit of floors female is noted for lower portion of the facial phobia being separated from the eye by two times of the and it's often shining in this area.
So yeah, above antenna with small UVM and pass apartment, we usually don't force kids into impressive.
Delicious.
OK.
So let's take a look at this facial phobia area. Since we were just talking about it and I have the specimen ready to go.
So in contrast to what we were looking at last time, you can see.
There, we'll just leave it here for a second.
So here you can see this facial phobia.
It's pretty wide, first of all to begin with and it's very.
I think it just shows up as very crisply defined and and if you were looking at A at a scan, you see that these edges are very nicely defined and this is relatively deep, and then it's.
So here if we look on this specimen, let's zoom in a little bit more.
We have the hair problem of the lower part, but I think we get the hint because it's so strongly defined.
So here is the edge of the facial fovea. This is the wider part up here, as per usual, and instead of just kind of wandering along and border to the eye, what you see is that it runs out. It bows out here.
So it's actually leaving the wide area.
Fairly far.
Inland and it's running in a very skinny way and runs back like this. So that means that the there is a shiny in this case area of integument between the eye and the maximum width of this distance to the facial phobia. That's fairly wide.
So if we look at a measuring tool, we'd say it's about twice, I think or maybe more than twice of the difficult to see because of the hairs width of this narrow part from the eye.
This is this is quite extreme compared to other species, so that's a good another good general character for this species.
And this is one that Easterners will see.
More commonly, and probably is a denizen of canopies that we don't tend to study very much.
We catch it pretty regularly down in.
The.
Or floor in the spring.
In Nice deciduous woods, OK.
Now we're gonna go for this notion of.
Deep pits touching one another or nearly touching one another on the back.
And here we go.
So you can see that many of these pits, particularly as you get this happens in general as you get to the anterior edge, pitting in general increases and can pile up.
Algal Chlorella Arata is a good example of that.
So even back here though, you can see these pits are almost always touching another pit somewhere in their diameter.
There are still little gaps there, but as you move.
Towards the interior edge.
So this is the interior edge.
We see that it looks like they almost all are touching. In fact, are just becoming a general surface busyness rather than even pits.
So.
That's a good. That's again one of the primary definitions of lugosa is to look at that. Then if we go.
To.
T2.
To see if it has a very wide depressed area so that distance from the rim to where it elevates.
Again.
Very unusually long. Really. A few mill back to looking at all the entering a species again.
Just have a little depressed trend down here.
Here it is.
It's usually you have this.
This is very typical where the sides, the depressed rim of the side.
It sort of bends back towards the rib, the depressed area boundary, I should say.
Bends back to the rib.
But here, right in the center line you can see.
75 to 80 percent, 90% not a problem in terms of that. That's where it is about there huge distance.
So that's our friend Rudoza.
Oh, let's look at the Purple triangle, which should be in a rectangular mode.
As opposed to what we were seeing, there's not a strong character of this species, but for the other two it is.
In contrast, so here we go.
Now we have a couple things.
One you can really see.
Here's the defining rays Corina.
That separates the triangle from the back surface that's vertical.
So this is the ventral face.
Here are the very nicely demarcated boundaries between the triangle and the lateral face.
And here are these very rectangular.
Created spaces.
Cells, if you will, by the striations typical of many, but not all.
OK.
One word.
Can only leave after they're all done.
Alright sigmundi, this is sort of my own personal nightmare species.
And the reason for that is the primary.
So let's go.
First of all, we'll go to the.
Spreadsheet to be easier to explain, so here's sigmundi I can't remember.
It's possibly that it's associated been associated in the past with willows, and you can see it's very close to Forbesii and Marie, both of which have lots of pits on T1.
And the primary way as we know, first of all students pitting 0.
So it's basically they're on top of each other.
So that's should be a pretty good.
Character, but you can see here for Betsy. I is also in that category.
Emery, not so much. Little gaps in between there, but certainly we can't eliminate it just on the fact that the pits are all jumbled next to each other.
President clear again for Bessie. I very similar to that.
And so we have usually when it's president cleared, it means that the outside and the inside of the triangle are very different, and so are defined nice and crisply.
And keep going.
Huntivia may be more acuniate than most, but this is the one the character in I think it might be both Mitchell and.
Whatever Labour's version of his revision is there, and it's a little difficult to see here because of Excel. But basically you're looking for the inner pine tibial spur.
So when we're looking at tibial spurs in these, it's almost always the inner one that is doing something interesting. The outer one seems to be largely just.
A nice little smooth curved thing and then the inside if something interesting is going to happen, it's going to happen on the inside.
Anyway, that's the case here.
The inner hind tibial spur, with a with bend or Tink in it, that makes it appear to be slightly S shaped.
Hard to see. There's the willows comment.
So the tricky thing is it is hard to see.
So let's see if we can see it.
Let me just look in the microscope, see if I can even get a hint of it on this specimen.
Otherwise it might not be worth it.
So if the legs are tucked close to the body.
Then you have a difficult time seeing these things.
I'll also point out that we are looking at the para type.
One of the paradigms so a parity is additional specimens that when the type was created, are also the same species that can be used for reference.
And material and I can see one of these inter tubular spurs quite well.
And I don't see that Bender kink that much.
About to maybe spend more time looking at these parent types. OK, so.
When we were looking at the property of triangle, here we are back in that same world of rectangular.
So here are these large defined striations running down very sharply demarcated.
Situation and on T1 there are a lot of pits, so that's pretty good density.
And then on the skew Dum, they basically we get a better angle.
It basically should be touching one another, all of them.
See if that is true.
Jump up here.
We well, the fact that we're having a hard time seeing this probably means that they are touching one another and making.
So we don't have the shiny interstitial spaces.
There's a little bit there, but that's probably the parapetal line, so I'm gonna. It seems like something to see will change the lighting.
So.
Move there and.
Open up 300.
Nice make this big.
Great. So we can see the pits better here.
You have a darn big pin right in the middle of everything, so we can try and get things to the side.
Things in focus.
It's a little bit hard to see.
I do see some gaps though.
But mostly I think any particular pit has another pit that it is touching.
It's not like we have isolated pits.
But I can see.
But I'm not thoroughly convinced that maybe it's always 0.
Let's take a look down here.
But it's pretty darn close.
So and look throughout these areas and we see most of the time it's touching.
So whether it's 100% or not, it's a little hard to tell.
Now the very tricky thing which I'm going to turn the specimen upside down. We'll keep the light on high.
Because we'll have to be at.
We had a high.
See a leg that is covered in pollen.
Here.
And.
We have.
To spurs. So it's a little confusing, but here is this almost always normal outer spur.
So this is the outside face which makes sense 'cause there's all the pollen in there.
Who knows what that is? 100 year old pollen then behind there is.
The theoretically kinked and it is not.
In this case, this is what I don't like about.
It's not as clear like there are some like andrina MACRA.
And andrina.
A very distinct.
Kind inner tibial spurs that you can go to the bank on this one has just always been like, OK.
You know it's wide here and then tapers off this line, not tapering equally. And it looks like there is a very slight kink in there. And if we look from the other direction, it's it's also curved.
But I'm just telling you that it is not an easy lift.
To see that thing.
I'm gonna go back.
And drop the.
Lighting down.
So sigmundee and now we have 2 remaining.
By Rihanna.
Which is very similar.
To to pick out a specimen here that's cleaner.
To heraclide so the key will be looking at the aselli area between the aselli and the.
In Tenney, let's take a look here.
By Rihanna, OK.
Yellow areas.
Yellow highlighted spots move this out of the way.
We.
So we have this situation that occurs also in her ankle eye. And so instead of having, we'll try and look at this in on Virginia and when we get it, instead of having that area between the aselli and the antenna being filled with lots of pits and lots.
Of striations of different kinds and bitterness.
It's relatively calm.
It's relatively smooth with.
Relatively small.
Well spaced pits in it.
So that's quite different and it's really just, is it this one or this one? Every once in awhile you try and second guess yourself as well.
Take a look at that area and go like OK.
Well, maybe.
Maybe there's a little bit of striations there, so maybe it's not what I think.
That's the value of having collections of things.
So and collecting a lot of specimens, because then you can look at variation.
So the phobia, so the next yellow one, the distance to the rim of the eye is pretty wide. So .7 to 1.2.
Another.
You can see we go back up here.
Oh my gosh, so does heracle I have that same thing.
So there's some redundancy in these characters.
Fortunately, the pressed area .8 to .9.
For actually I not that much different. You see .75 instead.
Difference between .75 and .8 pretty.
Pretty small.
And it has distinct bands.
White hairs on the sides of T2, which correctly I is not apparently given to or it's there's some question marks.
Like the pitting, this is the one that really separates it out from her.
Actually, I so rarely has very dense pitting on 2/1, whereas on spyriana it's quite widely spaced.
Now that's widely spaced for tracking, so three, you know, on average we're seeing 3 acceler differences 3.
Acce diameters apart.
And sometimes there's a note here. Sometimes hints of orangish on the integument, which means you have to watch out for.
Which is very orange.
OK.
So let's take a look at these things.
We'll start on the head.
And we have something queued up.
This large.
There's a finger.
Use a very dirty finger.
All right, so we want to look for this smooth area.
Between the this is a pretty good shot.
Scheme of andrina specimens.
So.
This area between the Aselli and the.
And the antennae. This area right through here.
Theory. You know, there's some scattered, relatively small pits.
It's reflecting light and.
That you can see it in a couple different places on the on the head and as well it's not.
There's not a lot of surface sculpturing.
There's a tiny bit though.
That's where you start second guessing things. If we look as was mentioned at the.
Edge of the eye to the bend in the facial phobia.
Here's a facial phobia, right?
So it pulls away.
So this distance here is much greater than one width of the.
Atophobia narrow part here.
So in other words, it's pulled quite a distance away.
It's not running close like some do.
Right when we now the very most definitive thing will be what's going on on T1 should be very sparsely pitted.
Compared to correctly I where everything is quite densely and very densely really pitted.
This should have.
Well spaced bits.
So many.
So much of the like individual life histories of these bee species is still pretty murky, you know, like, maybe it's on Willow, but, you know, you look at the records. It's like, yeah.
You caught it on Willow, but lots of things get caught on Willow.
All right. So again, similar to one of the other species that we were looking at, maybe Reni, you can say, OK.
Well, that's pretty dense there.
Let me change the lighting.
No, that's good.
So you say, pretty dense.
Well, in comparison to something that has just pits here and there. True, but.
When we look at the spacing, almost basically none of them are touching one another.
And if we use the small pit diameters, you can see that Yep, at least three often greater than three pit diameters apart from their nearest neighbor. So.
That that gives you a pretty distinctive hit on.
The species you can see our friend the rectangle.
And these rectangular cellular like structures here.
On the Purdue Triangle, OK.
Now we have 1 left.
For eastern ones, and who knows if someone actually bothered to do a bunch of molecular work, what they would find?
Hiding.
Amidst these track and granular, which I think when I think of Virginia, I think of like your generic track andrine.
Not nothing.
No one thing really.
Speaks.
So we have a moderate 2 to 3 fat tonero not like on the extreme end, but pretty narrow pretty fat.
And we have the long rectangular.
Cranie, as most do you have no border of the triangle.
So in other words, these areas when we're looking at the property triangle, we can't really see a clear raised line absence.
So that's useful.
And then when we're looking at the relative sculptural differences between the inside of the triangle and the outside, it's a very, very slightly more coarse than the outside. The inside is so also useful behind.
Tibia is brown.
That differentiates it here from the podies and this fact that you have a lot of these yellow areas means that it's it's just a process of elimination that gets you almost to Virginia, the T2 area, the depressed areas is .6.
And white areas pitting on T1 is sort of again right down the the middle of the line one to two pits apart.
So not on top of each other, but neither are we similar to some of these other where the pitting is quite distance.
And you know, I have a comment.
Very generic. So let's see what we can see in this particular specimen.
Here from many years ago.
Maybe it'll be done track and dream.
So we're here on the abdomen.
And we can see.
Here we don't have a fullest completest angle, but we we might change that.
The wings are pretty much covering in the other direction, but you can see that it's, I would say that's more like .7% or 70% rather than 60%, but it's certainly not 50% and it's certainly not up here at the top.
In terms of the depressed area and this area here, we're gonna have to move this to see if we can see our one to two pit diameter apart.
Sort of things.
And.
On T 10, let me just end that a little bit again.
One good thing about this class I've gotten better at moving things under the microscope online.
OK.
So it's supposed to be one to two pit diameters.
Yep.
That you could call it that. If you look in here, yeah.
While you are right there.
The cheap, like on the other notes on the species pages, yeah.
I just lost it.
Heroes lost it.
OK.
Well, we, we'll get back to it.
Sorry, I'll come back to it if I find OK.
Great and.
Totaling the wrong microscope.
Let's see. Did we have another feature?
Well, we had a fat but then ratio that was.
Again, moderate to in between.
See what we can see here.
And yeah, good. See that?
So here is the upper part.
Here is the lower part.
The lower part would appear certainly wider than many of the others, and the upper part isn't extreme.
So yeah, I think it's listed as.
Two, something like that. Let's go back.
So again, this sort of middling of the road sort of thing, oh, we look at the proponio triangle and.
Here we go 2 thin 2 to 3 sure.
Now let's go to the podium. Triangle. We're gonna.
Yeah, while you're sloppy thing, I found vertex with two rows of pix 2 rows of pits. OK.
That I don't even remember that. Does it say two rows of pits and the others have more or less the females of virginiana differ from those of Miranda by the more sparsely punctate vertex in two horizontal rows.
I was mm hmm and.
I think I'm listing a word in my notes and the usually shorter apical area of turga C3 four that you showed. OK.
Right here.
We have.
Oh my gosh, I would say there's three rows there.
It's a little bit difficult.
This is definitely one.
Two and maybe 3A baby ones.
They're tiny, yeah.
So I don't know.
I don't know when that one.
We are gonna look at the promotion triangle now.
OK.
So theoretically it's gonna be very difficult to differentiate the triangle area from the non triangle area, and there's no real raised line per SE on that boundary. On the inside, a little bit coarser, but not a whole lot.
And so you can kind of.
You can almost always draw this line from this corner. Down is gonna be the.
Triangle and we can. We can see that there is a there is some sculpturing differences here.
These are rectangular.
These are not, but it's not sharp and it's not a whole lot.
Obviously, difference in terms of.
Degree.
Of.
Sculptural.
So are there any questions?
Anything in the chat?
There's nothing in the chat.
Please pop in.
So now that was the last of the eastern ones as currently defined.
And people in.
Identify hopefully a lot more of their specimens.
In all these cases.
We almost always end up with a andrina species, Andrina track andrina melandrina species where we may be able to define a sub genus, or maybe not even that, but we're not.
We're not sure about the species and several new species have been discovered and are being actually written up in the east.
In adrenaline.
So don't be shy about calling things species.
Well, that David, our friend David, who has made so many resources and you keep advertising bum, bum including the amazing guide to the adrenal guide.
He is now on the eastern area of the country and so that adrina guide to the guide was made for a lot of Western specimens, so.
Hook up with David to.
Get some Easter specimens.
Highly well done photographs.
We love it.
Maybe he'll start identifying specimens for people.
I will leave him to speak to that he is in the chat.
There you go.
I think that'll be a great idea. Yeah, I do too.
And also yeah, so I I copy and pasted a lot of the little short descriptions from the species pages in the chat, but this seems like a group that we have really lush information on the pages.
So don't sleep on those.
I was all I got.
Right. You know, I just have a quick question for everyone that they can get their chat ready.
Just throw it into the chat is I'm curious about how often or how many times something rough that you guys have gone to the online saved.
Talks that we have given here to either I need to go back and look at something or figure something out, or just because you missed one, if you could just throw that into the chat.
Including that I never do that.
That would be great.
Because it gives us some idea about how much that's being that resource is being used as a archive and.
You know whether.
Yeah, just like is it?
Is it any?
Is it used at all?
I mean the fact that people show up means that.
They are fine somehow it it useful or entertaining.
I doubt that to show up for these sessions, but I'm wondering about the archived work and whether that's convenient, easy to find, that kind of thing.
You got a lot of positive, so people are I got. I got five out of six are saying they love him. OK. I'll also just add to that is I do most especially students that.
Start each year.
I know that they go back, which is all a great request for you. All. I have done a poor job of keeping track of what species we cover each time because other management while facilitating.
So if you guys wanna help make a table of contents.
Because you go back through videos and you are noting what species.
Talk to me.
That would be great.
I've wanted to do that for a while and they have not.
Because the past two, yeah. Then you could look up the table of contents like. Oh, have they talked at all about Andrina Rennie?
And then you can find out which show it's in.
Or maybe it's in more than one?
People are doing that.
Send them to me a spreadsheet.
Love it. Thank you.
We will make it happen, OK? Or just an e-mail. And then because they may only look at 1:00 and then, OK, they can send it to Claire and she can add it to some master list.
OK.
I mean it's it's sort of a a market with built in usability right 'cause you wouldn't be here if the idea wasn't useful.
So the expectations are that you probably would look at the videos.
I think it's more.
What are the random people who are aren't showing up for?
The live ones? Are they using these videos or not?
And I'll just say there's AI that could really help us.
The transcripts, the training it to use this these words, which again David has a glossary that would be a great thing to train it from. In addition to all of the other philosophies available.
If you wanna chat on the side, I have some prompts to give ChatGPT, but I think that there's probably better AI out there that has less environmental impact and we could get this done with a clever it friend including timestamps.
It sounds like the notes are also useful.
I saw at least one person saying that they use the notes.
Cheat Sheets are great.
Alright, good.
Yeah, good to see.
See that?
I mean, if no one was showing up that.
Are our marker 'cause? You know, you do have to spend some time to just come to the class.
And so we have a full classroom every time, like around 20 people consistently.
Nerds.
Hmm.
Next week, OK.
Thanks everyone.
Thanks for the feedback.
