Alexander, can you tell me how to distinguish between Trypoxylon figulus and T. medium and why the first species is shown here?

You can distinguish, of course. Either by keys with optics, having an animal, or by filling the eye.

For the first option, I give a couple of links:

http://biodiversitylibrary.org/page/15775437

http://researcharchive.calacademy.org./res...n_kostylevi.pdf

For the second, this is already personal know-how

. There are no real distinguishing features in the photo - the wrong angle. You can't see the face (specifically, the trim plate), which is the easiest way to distinguish females.
However, the relative size of the soil particles indicates the largest of the related species, T. figulus (T. medium and especially T. minus are not only rarer, but also noticeably smaller, and the soil particles should have been relatively larger.)

A stuffed eye is our everything

I thought that there were still some obvious signs of M. B., since the side edges of the platband are not visible in the photo. But the size of the soil particles is something exorbitant for me

I used Lomholdt (1984) for a long time to define them, but this is a reissue of 1975, and I thought that for such a group and territory, it is unlikely that any changes are likely enough. Ahn, no... It turns out that under the name T. figulus there were as many as 3 species hidden there and all my few materials from the accompanying collections were determined exactly like this

I recently picked up Jacobs 2007 (Die Grabwespen Deutchlands), and redefinition showed that almost all of my Karelian and Kola Tripoxylons belong to the rarer T. minus
And T. medium will still need to be searched...

Please help me determine the OS. All taken recently, in early July (except for the latest paper version)

1. Probably again Parabatozonus lacerticida? Probably a female this time, because she first sat near the mink?

2. ???

3. It seems to be a different view? Or is it the same as the previous one?

4. ???

5. Some kind of philanthropist?

6. Maybe again female Priocnemis sp.?

7. ??? From two angles

8. And why does it hang on your jaws so much?

9. Fairly large female, May 15

And more. The other day, a whole column of ants ran across my dacha. The width of the column was from 20 cm to half a meter, and the length I don't know what, but we ran through one place for several minutes. And everyone was rushing at high speed. That's why the pictures didn't work out - they were moving too fast!

Amazon ants Polyergus rufescens in a marching column during a raid on the Formic anthill. Here I have a video of a similar attack:

Very interesting ants. Their anthill is hard to find. On the surface, there are usually only "slaves" and rare Amazons. And only during the campaign you can admire their army. And you can trace the column's return path to identify the anthill.

Interesting video, thank you! I see - the Amazons do not kill Formica to death, as it was described in the famous children's book, but only rob! It was a pity that I didn't think to trace the final destination of the column - at this time, rain was gathering, clouds were running in, and I was not up to ants!

I'm afraid that my wasps, which are before the ants, are already lost among the many subsequent downloads - please identify someone!

It just seems to me that if this feature worked well, it would not fail to be used in other, more recent keys as well (Jacobs, 2007; OLSZEWSKI and PAWLIKOWSKI, 2014) - the second source AVA gave a link to

There is no need to argue, just a keeled intertubular tubercle is a sign of other species. Of the European species with this trait, only Trypoxylon fronticorne is known, which belongs to the frigidum subgroup of the figulus group. In Central Asia, there are also T. amankutanum, T. eugeniae, T. gussachaos, and T. turkestanicum, and in the Far East, T. frigidum and T. pennsylvanicum also belong to the figulus group, although they are different subgroups. In addition, there are also T. exiguum, T. koreanum, T. rufimaculatum and T. varipes, which also have a keeled protrusion between the antennal pits.
In fact, this genus is one of the largest and most systematically complex.

1-yes, it is a female Parabatozonus lacerticida
2 - Ectemnius (Clytochrysus) sp.1
3 - Ectemnius (Hypocrabro) sp.
4 - Ectemnius (Clytochrysus) sp.2
5 - Bembix rostrata
6-yes, probably also Priocnemis sp.
7-Tachysphex sp.
8 - it sleeps like this (many wasps and bees do the same)
9-Vespula vulgaris-female founder

The Amazons sometimes kill. Sometimes formica's head is bitten through and he begins to spin constantly or fall on his side. But this is rare. Losses are usually low on both sides. Formics often offer little resistance. They're just running around in a panic. They often try to take the pupae outside and hide from the Amazons. I saw formica workers running out with pupae and climbing up tall blades of grass. We sat there for a few pieces until the Amazons left. The same formica nest may be robbed several times as the pupae mature. Amazon scouts monitor the nearest formic nests and if they find pupae somewhere, they return home and the Amazons begin to get excited, soldiers come to the surface and hike... The Amazon is one of my favorite species. They are very interesting to watch.

. . . They often try to take the pupae outside and hide from the Amazons. I saw formica workers running out with pupae and climbing up tall blades of grass. We sat there for a few pieces until the Amazons left. . .

Still, the ants are smart! They understand that the invaders need pupae, not larvae, and they also understand how best to hide! In my opinion, eardrums are the most intelligent of insects. For example, I noticed that polista and vespula wasps, as well as hornets that have made a nest in a summer cottage, soon remember the owner of the dacha and do not react to him, even if he accidentally touches their nest! And if a new person comes, then the guard may be unhappy to buzz and even fly around him!
