Identification of Hymenoptera (wasps, bees, ants)

Surroundings of Kirovo-Chepetsk, Kirov region. May 4th.

good morning. Tell me what kind of Melecta? South of the Krasnoyarsk Territory. Early May. On some small steppe flowers (something from the labial flowers). The female. quite a large one. 15 mm. Her face was covered with light, thick hair, and her eyes were sparsely raised on the trim. Shield with two spikes hidden under the hairs. 2-3 tergites with 2 old spots, 1, 4, 5 with one white spot.

V. A. " by garlic "- I'm not sure that this is a genus of Melecta. We need to use the keys to chase her away....

Variant of M. luktuosa. I'm not sure, though.and " by garlic "- I'm not sure that this is a genus of Melectum. We need to use the keys to chase her away....

Yes, again a male of the genus Andrena. Up to a view based on such photos....

I constantly have a problem between Melecta and Thyreus, but the second one is almost naked and the signs are different. I just gave all my friends for comparison so far, I don't even have anything to compare them with. But I've never seen this type before. Bees are really beautiful and quite rare here, so you always enjoy the next capture.
If not Melecta, then who can it be? I looked through DV and Europe.I could not find a combination of such an arrangement of spots on the abdomen. M. luctuosa? something with a stretch, but my specimen has a couple of spots on a number of segments of the abdomen.

Sadly... We have 60 types of them in our region!
Sleepy now you will find figs, but in the wind with your hands better can not be removed.

It's probably Lasioglossum / Evylaeus (Halictidae)? [/url]

And also Andrena, just in case.

There was also a Nomada that was unfamiliar to me, with a total of 28 species in the region's list.

There is a version-Nomada leucophthalma, parasitizes Andrena clarkella. These andras are also flying now (there is a photo).

I sometimes also have these two genera confused, especially when you put them in a box by birth without looking closely.
Well, yes, I've never seen such pubescence in Thyreus, and in general it's Melecta.
I also turned your copy on the "green" and DV and also did not come to any conclusion. Frankly, there is a lack of literature on bee colonies in Kazakhstan and Southern Siberia. Kazakh material often comes up with no problems, but there is no such type in the European part.
Evgeny, can you still gather your strength and catch bees for me from your region? At least an andrenid, megachilid, and apid (except bumblebees). At least banals, which is not a pity. It's easier for me with a copy than with a photo. Maybe I don't know what

I was not too lazy to review the collection. I don't have a similar look. But this is not an indicator. I have a total of 29 types of nomads. If you are interested in the genus - catch it. We'll figure it out. I love this family very much

I also catch nomads, but so far I haven't even thought about sitting down to determine. It seems to me the risk of a large "span" in the definition of the view. Although in the European part, everything can be simpler than in our country.

Yes, I remember your wish . So far, the fees have not been released on a massive scale. And these comrades like melekty, thyreus, celioxys, antidiums are rare for me. Most of the above, plus megahilid gave their definition, I think that will help. And I catch andren, you can try something on them. So far, I'm sending all the surplus money to Dima Sidorov in Kemerovo. He identified some of them here, but I can't find some of them in pictures, and it's hard to find any information based on the description or ecology. Also, the group is going to haliktid, but this is generally an ambush
By the way, how are you doing on the Hyleuses?

Also, the group is going to haliktid, but this is generally an ambush

In the identification of insects DV volume IV part 5 it is on halicts very, very much. I recommend. Yes, and so there is work on them.

yes yes yes But even with such a great job, I have problems in some instances. Often the variability of spots on the face is confusing, and sometimes you just need to show what it looks like. Yes, and English in its own translation is scary

I'll take a look in my storage bins. But if there is something on them, I will be grateful! :-)

In any case, I do not stop catching, so I will definitely save in reserve!

yes opened, thank you!!! It will come in handy of course. I think I have very little information on this kind, especially in Russian. I'll check it out again at home. Thank you again!

I didn't notice about Nomada leucophthalma. The funny thing is that it's basically similar. I was confused only by the color of light spots on the abdomen. For this species, my collections are large and all specimens have bright yellow spots. Your spots are pure white. It would be nice if the specimen was from the south, in southern specimens the yellow color often turns to white.

  

I also met such a specimen, with reddish spots behind the eyes and the same color spot on the scutellum (or shield? I don't know what to call it correctly):

 

Immediately there were questions about males Nomada lathburiana. They should have two yellow spots on their scutellum, but mine don't. Maybe it's a different view? Or is it just hard to see?

And also, poke me where to read, how to properly catch them and spread them out, etc. If you can, I'll send them for study.

Ancistrocerus parietum? Crimea, Sudaksky district

Good evening!
Please help me to "call" them.
Today, Moscow region.

Skills and, accordingly, experience of fishing are not yet available.(
Yes, and images that are adequate for identification, with suitable angles, too.(
All that is, 100% crop:



Osmia bicolor was another specimen:

Good afternoon, please identify. N. Novgorod, today.
