Colletes cunicularius, I suppose?

Colletes cunicularius, I suppose?

Famously you get, I'm sitting here with them now, the males are sorted out by "male parts" and then not everything is clear, but here it looks like this

Well, I don't pretend to be accurate, but given the date, who else can it be?

Colletes cunicularius, I suppose?

I'm not sure. Now we have andreny fly, I think that some of them.

I also immediately thought of him for some reason...

Evgeny, collets are certainly a very difficult genus, but there are no problems with cunicularis. Early spring species (we fly in April), mostly on flowering willows, and the size exceeds the rest.I distinguish it immediately, but I suffer with the rest.
The same garbage by the way with Hylaeus nigritus. He differs from everyone easily, and then zhopa

It's probably in me white envy says, I just can't define them ))))
I looked at my cunicularius really, the capture dates are mid-April-early May! ))
I have no problems with female hyleuses of H. variegatus, sorry for the rest, a little closer, a little full-face and a little under the binocular)))

Yes, cunicularius is spring, the rest are summer. Well, we have in the north mainly on compound flowers.
H. variegatus goes without saying. True, there is another species with a red belly in the Crimea, but there the head is very elongated.
And nigritus is also hard to mix up

Well, I don't have nigritus, it seems to only reach the Urals from Zapapa.
I have a problem identifying H. nigrocuneatus and difformis by holding instances in my hands.

I'm still going to think about it. It is necessary to sit down quietly for an hour or two. And in the last few days, it's just time for chatter.

Good evening,
It is possible or not to determine pipilschikov from the photo

Yes, Camponotus ligniperda.

Alexey, I sat here with these copies and this is what has happened so far. These specimens are clearly from the subgenus Vestitohalictus according to Pesenko, found in this subgenus for China in English.read the article with the keys
I have three options
1. actually vestitus but confused by the ratio of length and width of the head. In mine, it is not transverse, but more than a ratio of 1:1. Is H. tectus a synonym for this species??
2. pseudovestitus, but the head is broad, the same width as the abdomen.
3. pulvereus however, the casing is completely metallic, without a brown tint.

Also sat down
I didn't look at the results of your definition, but I came out in the same place.
I decided that it was probably Seladonia pulverea. I used the identification of insects of the Far East and Pesenko's work on the genus Seladonia of the Eastern Palearctic. I don't have any articles on Chinese types(by the way, will he send them? badajkin@mail.ru).
And yet - these works do not include Seladonia vestita for the region. Or you don't have East Palarctic anymore. tectus Radoszkowski 1875 yes, as far as I understand the synonym.

Well, in general, the best option you know yourself is to catch and catch in the summer. There will be 2 types in your hands - you can definitely distinguish them.

So far, I'm also leaning towards this view.
Lasioglossum or Evylaeus morio?
Do you have this type there?
skynu

 
Lasioglossum or Evylaeus morio?

I haven't seen it in the Leningrad Region. To the south, the view is quite ordinary, I have it from the Saratov region, Ukraine. In small batches.

I called it morio for now, because Pesenko has a lot of similar types there. I've got about two dozen of them there that look similar to each other, but who knows? you will also need to search for literature in this group. What about the generic name?
Did the article get through?

Thank you, the article has reached us.
Well, with childbirth, "there is no order, as there is no". In the works of domestic specialists, Evylaeus is usually distinguished as an independent genus. In the works of foreigners usually as a subgenus in the genus Lasioglossum. I wonder what's the right way. I write as a separate genus.

We do not have many species close to Evylaeus morio. I'll have to look again.
In general, they would catch bee trifles (at least banals) for me. It would be easier to talk

yes, I catch everything, not everything probably flies... ))))))) In the evening at home I will get in touch ))
and about the banals here it is difficult to say)))

The breeding experiment was completed today.
Can someone identify it?

Arge ?ustulata

Surroundings of Kirovo-Chepetsk, Kirov region. April 29.

Colletes cunicularius, I suppose?

I'm not sure. Now we have andrena fly, I think that some of them.

I came late to introduce doubts and confusion... And by the way, yes, - doubts. I looked at my reference book K.-colletes K., although he is early spring, 1) the back is not so red, grayish, 2) the paws are not red, 3) they do not hang out on the trunks, but in colonies on the ground.
Total - why not, for example, Andrena clarkella or nitida? (with a light brush on the muzzle of his face) - the truth is also doubtful, according to the shade of the pterostigma, but Andren is also a cart and cart.

"Halictus" vestitus Lep. and tectus Radoszkowski 1875, as it turned out, appear in the lists. http://www.faunaeur.org/full_results.php?id=232346 as valid views. without genera-subgenera, though. so please check with us on other issues as well.sources. Probably it is better to adopt a crushing system for the birth of Uv. specialist Pesenko, if for everyday reasons-the genus halictus is very indecently large-everything is in a heap about nothing. And if not for everyday reasons, but for example picking the genitals ( theirs) - even their relative sizes are very different, except for morphology.

Yeah, thanks. Well, Lasioglossum or Evylaeus tried to find out applicable to a certain species, because on the Internet I met instructions in conjunction with both genera, excluding of course Halictus proper. Alexey explained to me that it is not always possible to separate Evylaeus from Lasioglossum as a separate genus. Nevertheless, I will focus on the names suggested by Pesenko.
True, for me, the exit scheme seemed rather complicated, even in the market, so I do a little, maybe not right, but easier for me .I use the" green " method to identify specimens, find a group of species that are suitable for signs, and then search in the text for Pesenko to find the names of species and accordingly go to the genus, and there I check the signs of this genus, well, so far this approach works

I came late to introduce doubts and confusion... And by the way, yes, - doubts. I looked at my reference book K.-colletes K., although he is early spring, 1) the back is not so red, grayish, 2) the paws are not red, 3) they do not hang out on the trunks, but in colonies on the ground.
Total - why not, for example, Andrena clarkella or nitida? (with a light brush on the muzzle of his face) - the truth is also doubtful, according to the shade of the pterostigma, but Andren is also a cart and cart.

Here, my cunicularius males are slightly different in color, they do not have red, they are gray, gray like that. I'll have to look at everything else at home later. Yes, and the body of some kind directly I want to say Andrena.
I can't make out the dimensions of 2 and 3 radiomedia cells. They seem to be equal, but for some Andrews they are also very similar in size.

Most melittologists follow Michener's system, but there are only two genera: Halictus (=Seladonia, = Vestitohalictus) and Lasioglossum (=Evylaeus). Such a division of Halictus s. l. is absolutely justified (in the sense that at least it is not one genus), but whether it is necessary to divide even further is a question. Probably the experts in this group will be better able to answer this question. I once asked Pesenko why the family was divided, and he said that for convenience - with all due respect to him, such an answer seems to me unfounded. But our specialists (Astafurova, Proshchalykin, etc.) use its system, so there are probably grounds for fractional division.

Kostya, there are a lot of nuances here.
In specimens from the north, the pubescence is darker. Yours may have a gray pubescence of the back, but mine (north of the Leningrad region) are exactly like in the photo.
As for the paws. Again, I reviewed the collection and made sure that the male cunicularis legs and the first segment of the paw are covered with reddish hairs on the inner side. If you do not look at it with magnification, you get the impression that the legs are reddish. I looked at these photos - they seem to have exactly the same pubescence.
Well, as for the trunks, in April, males of many species, including the "earthmoving" andren, often warm themselves sitting on the southern side of the tree trunk.
And if this is a birch tree and there is juice, then they generally fly together

However, it is difficult to argue with the main thing. On the first impression - colletes. I looked closely - maybe Andrena. A copy would be in your hands to spin

I have redheads from the north of the Karelian Isthmus, and grayish ones from the Yaroslavl region are more likely.

And what I want to say andrena....Well, in the 80s, I tried for several years to define this species as an andrena.

Hello! Between 25/04 and 07/05/14 (I was away), an insect of approximately 14 mm (8365) out of 8385 hatched, with a diameter of approximately 10 mm. Who is it? On the insect's antennae are "claws" (8370, 8388). What does he need them for? I've never seen such a mustache before. Thank you very much! ( Many thanks to Proctos for identifying parasites earlier).

Eumenes, male. Almost certainly Eumenes coarctatus coarctatus (for a sure definition, you need to look at the dotted line of the last segment of the abdomen from below and the pubescence of these very "claws" from the inside). And he needs" claws " on the antennae so that it is more convenient to cling to the female when mating.

but the bee still intuitively looks andrena.

You're probably right.
I'm generally a slow-witted cop, I need to turn the copy under magnification before my eyes, think about it, look through the literature, check and double-check it ten times...
According to the photo it's not mine at all

Fellow experts, I read your comments, and I thought: if everything is so complicated, then how do you distinguish colletes from andrena by the number of copies? Is there any reliable indication ?

~"only views are real" (c)

What makes you think that? I've been doing a little research on plants, so there are a lot of groups where practice shows that species are not always "real", but genera, on the contrary, are very clear and evolve discretely. Why aren't taxa like crocodiles real? Each species is real, and "crocodiles in general" - a figment of the imagination of taxonomists?

I do not call for discussion, so as not to breed a flood.

As for the discrepancy between the ranks of taxa in different groups, I agree; I myself once wrote here that one genus of Andrena is no less diverse than the entire order of cetaceans. And in no case did I call for refuting Pesenko's system in my message. Using generic names like Evalaeus or Seladonia doesn't hurt anyone.

So how do you define them? Catch it?

I don't define it myself. Sometimes specialists help. But again, only by photo.

Then I don't understand anything at all. Alex 2611 won says you can't see through the binoculars
