Identification of Hymenoptera (wasps, bees, ants)

The weather is terrible. Recently, there was snow, but in the daytime it was no higher than 10 degrees. The whole spring season is down the drain.

Same bullshit. After +30, it got colder to 8 degrees and the third day of rain. I, as if on purpose, the second day off. I sit and stare out the window and swear softly. Such plans for these days were....

  RoPro, also the other day saw several sitting and drilling a dead cedar. I spent a lot of time goofing around and came to the conclusion that this is a bracon (Braconidae) from the genus Glyptomorpha. Then I got stuck. So if anyone can clarify or straighten, I will be glad!

Thank you. They also gave us this information :

Nooooo! Dasypoda does not have such venation of the forewing.

Venation of the former wing is just typical for Dasipoda... The only thing that bothers me is the torn bandages on the tergites... And at hand, as luck would have it, there is not a single green and articles on this kind.... Conversion of three radiomeds. I can imagine the cells pretty well. So the shape of the two when merging is completely different... Pubescence of the hind legs-too pronounced for andrena... But it is typical for dazipods.... The question is only in the form... I caught similar bees in the Novosibirsk region and in the Altai, but similar ones do not mean the same ones... But this is all fine with the working version. Following the path of Andrena - you will go far.

Alexey, I'm afraid to ask, did you catch the dazipod yourself? Under a microscope or at least under a magnifying glass examined?
Here I am now holding a large entomological box, a quarter of which is tightly packed with dasipods. Even habitually, they are very different from Andren and from this photo. Okay, that's not an indicator. Well, then look at the back leg. The female is in front of us. The photo shows a typical leg of Andrena. Exactly the same in dozens of species of andren. And nothing to do with dasypod's leg. If possible, just look at the shape and pubescence of the lower leg and the first segment of the dasipod's foot. Nothing to do with the photo.

Venation of the former wing is just typical for Dasipoda...

Well, the main thing. After reading this phrase of yours, I doubted that the area of your interests is Apoidea. Deal with bees and so not distinguish between the venation of different genera of bees. Well, let's watch it. In order not to complicate things, I will use the outdated terminology of the "green" determinant. So, venation of the front wing:
In the photo, the first return vein flows into the first radiomedial cell.In dasipods, the first return vein flows into the second radiomedial cell.
In the photo, the nervulus is postfurcal relative to the basal vein, while in dasipods it is antefurcal.
In the photo, the width of 2 discoidal cells is one and a half times its length. In dasypods, this cell is very elongated and the width exceeds the length by at least 3 times.
Well, on trifles, you can add that in the photo (as in Andren) the cubital vein is strongly curved, and in dasipods it is almost straight.
All this in general gives such a different character of venation that it is almost impossible to confuse it.

Thank you. They also gave us this information :

I doubt something, primarily because of the small size of Atanycolus

. I think that I came across Andrena pectoralis Schmiedeknecht, 1883 in green. Isn't it more correct now than Andrena limata Smith, 1853 ???

Well, yes, like in the photo she is Andrena limata Smith, 1853.

I doubt something, primarily because of the small size of Atanycolus

Well Atanycolus are fairly large riders (5-12 mm). These are parasites of podkorniks. This genus is characterized by a peculiar shape of the first segment of the antennae:


And Glyptomorpha are not usually found in the forest, they are parasites of drillers of herbaceous plants. They look something like this:

true, this one in the photo may be from Vipio, but this is not so important

Better - on the side. Spike on the bottom, almost like a myrmick.

Alexey, I'm afraid to ask, did you catch the dazipod yourself? Under a microscope or at least under a magnifying glass examined?

Yes, Alexey, I did. Participated in expeditions all over the USSR and not only....
Examined and even dissected, and dug up nests, and made plaster models of nests do not swear! I have already written that I am currently engaged in restoring knowledge and data. The fact is that if the "map lay down" in a different way (I chose a career, not science), in 1986-87 I would have defended my dissertation on bees. Rather, it is about interactions within a colony of the same species and in mixed colonies. But what was-that will not return. Now that I am retired, I have decided to restore my collection of insects and my knowledge, observations and experiments. BUT certainly not for the disser, but for the soul!
And dasipods, as far as I remember, only about 30 species were described, there were a little more than ten in the collection! And please, namesake, choose your questions carefully, and even more so, choose your answers very carefully and try to avoid imperative comments.
Best regards,
Alexey

For barry
Based on the photos shown earlier, I excluded Cryptopone. In the second photo, the spike (prong) is clearly visible. Hence, the genus Ponera. In Ukraine, there is definitely Ponera coarctata (widespread). Perhaps there is also Ponera testacea, but they are yellow or reddish. And everything. I came to the conclusion that it is Ponera coarctata.

I apologize if I offended you.
Alexey, but you will agree that if you do not touch on my harsh tone, then in essence I am right. The wing venation of the bee in the photo is very different from the venation of the wings of dasipods. Even if you take all the Palearctic species, you can discard the location of the nervulus. As for the location of the 1st return vein and the shape of the 2nd discoidal cell, there are no options. Not dazipoda. Believe me, in addition to viewing the collection material, I also watched 6 works on dasipods. If you've read my answers, you may have seen that I'm not peremptory. I usually answer "probably", "probably", "probably", "it looks like". But there is a very big difference.
By the way, if you need work on this kind, I can send it to you.
Once again, sorry for the sharpness.

Well, yes, like in the photo it is Andrena limata Smith, 1853.

I was given a suggestion that it might be A. nitida, that many of the signs in green are already outdated. If you have nitida in your collections, see if it can't be?

As for the dispute that has arisen about Dasypoda or Andrena, I am completely on your side. There can be no other options than Andrena. Digging in the teniandren subgenus

I was given a suggestion that it might be A. nitida, that many of the signs in green are already outdated. If you have nitida in your collections, see if it can't be?

In the specimens I have identified as A. nitida, the main distinguishing feature is clearly visible - the lower part of the hind tibia is pubescent with white hairs, and the upper part is black. With a well-defined border between black and white hairs.
However, there are a few specimens that have white hairs on the hind leg, but they are not many and they are all over the lower leg. I put them to A. limata, but now I doubt it.
In general, the more andren you watch, the more questions and doubts you have. Oh, I wish someone would do a revision of the genus on the scale of the Palearctic.

Yes, but don't you use Fauna Ukrainy ? There, the keys are a little more convenient, and full descriptions of species, and for similar species, the descriptions contain differences. The differences between limata, nitida, thoracica, and assimilis are not limited to pubescence. The language, however, is Ukrainian.

Digging in the teniandren subgenus

"Subgenus Taeniandrena of Eastern Asia" есть?

there is no such thing. If there is in electron, I will be glad
Alexey, I now catch almost everything, I will try to collect for you everything that will be useful. True, it will all be on pins and needles and not on a large scale.

Night work begins. I won't send it to you until Monday.
Thank you for any copies in any quantity. Not on pins and needles, I hope?" If something happens, I will compensate for the loss of pins with new pins.

Okay, we'll figure it out there
Today the sun came out for 5 minutes and caught another limata on dandelions, before that there was not a single instance, and here in the spring there are already two catches in different places )

Alexey, do you have such types as praecox and helvola? If so, how are they fundamentally different? Calluses are already on my eyes, I can't understand.

You know how to hit the sore spots.
Either both of these types, or some one we have and is quite common. There is a lot of material. I can't tell them apart. At all. Several times I made decisive attempts to deal with this pair and each time I suffered a crushing defeat. Even with the subgenus Micrandrena, it is much easier.
If you have any thoughts on this pair, please contact us immediately.

Kostya, I've never seen a Halictus with such white bands at the base of tergites in our latitudes. But among Lasioglossum there are plenty of them.

Hello, Alexey! Thanks for the tip with the bandages - I completely forgot. Sobsno and was like a question - and why not..)

Hello, Alexey! Unfortunately, I have a problem.the collection and books are not at hand. As it happens , I will try to return to this issue with specific suggestions)) And so, and in general without keys, it is necessary to be silent)

well like still not Halictus

Surroundings of Kirovo-Chepetsk, Kirov region. June 1st.Fine, approximately 10 mm.

ichneumonidae, quite similar to Tryphoninae. I can confuse Ctenopelmatinae (due to the lack of specialist help) because I do not really represent their habitual generic diversity.
...Something I'm not sure about anything at all, not just insects))

About the benefits of spearing on the Andras (and partly Halikts).
Colleagues! Returning to this topic, I can say the following. If the tables of genera are still acceptable, then the tables for species are not confusing or outdated! Just the description of these (my point of view) tribes was not based on holotypes, or even paratypes. In some cases, the authors were based on syntypes (!) - which is no longer acceptable, and sometimes on individuals defined as a particular species. The result is that we have what we have. Confusing keys, confusion with species, and so-called sister species that can't be distinguished without a bottle... The preparation of the green determinant is a titanic work in itself, worthy of perpetuation, but the fact that the basic information was not always false is not their fault, but their misfortune... In the 80-ies, when I was actually closely engaged in bees, I could not identify a number of individuals IN PRINCIPLE. I came across the "third solution" in dichotomous tables... The result was this: I just threw two genera Andrena & Halictus, and as it turned out, I did the right thing. I focused on megahills and anthophorax +. Xylocopes. I managed to distinguish these groups clearly. And in some cases, the materials were identified as new forks. So hp small male Liturgus, which was collected in the North Caucasus and a female antidiemorphic species from Armenia ...

And how were megachil and anthophor determined? I'm not too happy with "green" for these bees either. And tetralonias and eucers are completely problem

Again I return to the old topic, I was told that A. bimaculata and A. morawitzi are reduced to synonyms. Alexey, have you heard anything about this? I have both of these types and they differ very well in appearance "in green", but I can't understand why or even if this is the case?
As for praecox and helvola, I have instances defined by a specialist, but I can't understand the main differences. In green, it seems that each type is described in different words, but the essence remains the same, it seems that you just need to wait. But for two copies, it seems to me that the person still missed, it will be necessary to check with him again. Perhaps we should look for males and look at the genitals already, so there were cases when only males saved, but while there were only females, everything was fine.

Anthophores are an ambush for me, and megahills sometimes bring such surprises ))) But I think I have this problem due to the lack of proper amount of material and little practice on them. Perhaps if everything was simple, it would not be so interesting

Further specialists I think will specify

I think it is more correct to ask: And for what groups of bees can "green" even suit someone? After all, eardrums on average are studied incomparably worse than beetles - I was stunned when I looked at the year of the description of Andrena magna. But this is a healthy critter with a large range, quite long (2 generations!) In short, here you need to look at the reference material, and if possible-and standard, study systematic works, etc., etc., and "stick" to the pain in the eyes and in the brain in the tables of "green" - an unpromising occupation. Although, as a basic source, you need to start from it (which can not be said about beetles).
