Identification of Hymenoptera (wasps, bees, ants)

Interested in parasitik near blestyanka (superfamily)

Is it possible to identify the Formica ant species from these photos ?? South of the Penza region, the edge of an oak forest on the root bank of the river (southern exposure) beginning of July.

Ciscaucasia, summer(1-June, 2-August)

Krasnodarskiy kray. August

Please allow me to use this invitation. I present photos (according to my understanding) of nymphs. This female was captured on 30.08.2018 in the vicinity of Novobikmetovo village, Buraevsky district of Bashkiria. Did I make a mistake in the definition?
1) The mandibles are slightly concave in the middle of No. 102902, but the roller is not visible (on the rest).
2) P. albellus and biglumis disappear, because the stripes on the back are pronounced.
3) The mandibles are black, the lower legs of the paws without black spots; hence, not riparius. and not chinensis
4) There is a yellow spot on the cheek. So either dominula or nimpha.
5) The sawyere is darkened. Hence-nimpha. Unless, of course, I made a mistake in point 1.

Both are Crabronidae, but I can't guarantee the exact species, since the necessary signs are simply not visible.

Thank you very much, the floor is there, up to Rod enough. Here is another small crabronida(1 and 2). I suspect that they are the prey of palarus(in the 3rd picture)?

I once met a very large wasp (more than 2 cm). I gave you only one shot and that was when I took off. But you can see the pattern on the back. Is it possible to define up to a view? I suspect that this is one of the cryptohils? Ciscaucasia. If anything, the file name contains the date, month, and date(the first 3 digits).

Here are three more wasps. Ciscaucasia. Approximately?

With pompilidami plugged, maybe with goncharnaya who can tell you? Ciscaucasia, autumn, rather large (more than 1 cm)

Dear professionals, I appeal to you for help again. This insect was caught on 14.09.2017 in the Aurgazinsky district of Bashkiria. Less than 1 cm. Sorry about the quality of the photos. Can I use them to determine the view?

For the middle band would say L. calceatum or L. albipes, but you have possible options.

Mellinus arvensis
