Dear colleagues, this insect was caught on 16.06.2018 in the Krasnokamsky district of Bashkiria. Is it possible to determine the view from these photos?

Dear colleagues, does silence on this insect mean that none of the forum participants have encountered such an animal, or is it impossible to identify even a family from such photos?

Ciscaucasia, hoplite?

There aren't enough angles. Maybe also Osmia.

No, 4 is Lithurgus.

3-probably Hoplitis.

If you are satisfied, then:

4-Tenthredinidae
5-Ichneumonidae
Unfortunately, the data for a more accurate definition is clearly not enough.

I do not know any Vietnamese ants.

I can't tell the formics from these photos. You need to look at the hairs.

Bigger, of course. It's a female serviformic of some sort. Females are larger than the workers. Most likely it is Formica cinerea or Formica rufibarbis. But not exactly defined.

Rather, Formica rufibarbis, I met such workers on my site and identified them accurately (the photos were better), but Formica cinerea is not yet in the photo collection! And in photos 6.1 and 6.2, I also think Formica rufibarbis with a dried worm. Thanks) And I hope that someone will help with Vietnamese companions

Why guess? Just catch the worker and zoom in on the underside of the head. If there are protruding hairs-Formica cinerea, if there are no protruding hairs-Formica rufibarbis.

Outgrowth of the forehead, not the platypus. It is visible in the photo under the left scapus. Well, habitually it is Lithurgus. It's just that there's probably L. chrysurus, and you might be thinking of L. cornutus, they're a little different.

Yes, Osmia males. The first subgenus is Helicosmia (such as O. caerulescens), the remaining subgenera are Osmia (such as O. bicornis, but there may be other species, they differ well in genitals, but not very much in pubescence, you need to "fill your eyes").

And how do you distinguish between them ?

The male Dryudella stigma has relatively longer middle segments of the antennae (in particular, the 6th one). But in such photos, this is not clearly visible, because, mainly, thanks to the "stuffed" eye.

Thank you. Last spring (at the end of May), Osmia bicolor flew in the same clearing. Could it be their males (or should they have a black head like the females)?

Yes, very similar to the male Osmia bicolor. And I didn't even realize (we don't have this species, and I only have its female in my collection).

Can we define Tachysphex ?

No, according to the photo with inaccessible features (the structure of the bottom of the legs, the pubescence of the top of the propodeum, the shape of the platypus), there are practically no guarantees, since there are many species that are similar in general habit. Moreover, males are most reliable only on the genitals.

This is one individual! My son brought it from somewhere, there was only a microscope at hand, a camera in repair)

12.04.2019 19:12, Кархарот

I understand (the first one wasn't yours). You most likely have either Osmia bicornis or O. cornuta, but they are best distinguished by their genitals.
