Identification of Hymenoptera (wasps, bees, ants)

If I understood correctly the " median field of prm. segm." then just go to manikatum

Sandy soils, pine trees.
Without much hope. And suddenly! At least until Rod.
Like the version from teapot-Chrysis angustula?

So is it worth taking a look at the smooth or shagra-trained midfield?

And yet, I didn't find a topic in the Images of insects where I could post more photos.

Are you absolutely sure that the photo is Tapinoma? Today I took an ant from there and ran it through the determinant (my first experience ). It turned out to be Lasius niger. Maybe?

As I saw at the end of the abdomen there are no teeth, it turns out that this is the genus Chrysura sp., but the view is not very similar to this color, I was more struck by the date of shooting April, spangles are very thermophilic

Hello! Is it the stone cuckoo (Bombus lapidarius) or the stone cuckoo (Bombus rupestris)? Today, Mordovia, on the edge of the forest.

Bombus lapidarius. The cuckoos will fly later, in May.

Thank you very much. New point, for the Red Book view

Since the platypus and the tip of the abdomen are not visible from below in the photo, I looked at the stalk. In lasiuses, the stem is in the form of a vertical plate. Just like the formics. Tapinoma has an oblique and rounded stalk. The front edge of the abdomen seems to lean on the stalk, partially covering it from above. I concluded that the photo shows a tapinoma. If possible, consider the lower edge of the trim under a good magnification. The tapinoma should have a small notch. The nigger doesn't have it. In addition, the anal opening at the tip of the abdomen in Niger is surrounded by a corolla of hairs, in tapinoma - in the form of a slit. These are the main differences.
I started from the shape of a stalk. In the photo, it is not the same as that of the Niggers, but it is very similar to the"Tapinomsky".

And I didn't see a notch in the trim. But there is one thing-maybe there are two types of ants

B. terrestris or B. lucorum?

More likely Pseudospinolia neglecta

I don't think there are two types of ants. Apparently I was wrong. I looked at the photo again. Of course, the niggers of the first generations of the family are always much smaller and slimmer than the "ordinary" ones, but the stalk is very confusing. He's not that kind of guy. Don't you have a profile picture of an ant with its belly in normal condition (not turned sideways)?

There are still photos in the profile, but the stalk on them, alas, is not visible (my legs get in the way). I'll try to take another picture, if I can post it.

Good day. Today I photographed a bee in N. Novgorod, please identify it.

It may be Colletes cunicularius (Colletidae)

There was a question about these bees. Very similar to the male Andrena vaga, but much smaller in size, and the antennae seem to be longer. Another species-genus?

And also similar in size and shape to them, only red.

I don't know if it's Colletes cunicularius or some kind of Andrena

Is this a male Nomada lathburiana?
