Identification of Hymenoptera (wasps, bees, ants)

Some kind of undefinable membrane, very small 5-6 mm from the head to the tips of the wings. It looks like a sawfly, but there is an ovipositor. Mustache with a strongly enlarged third segment. Photos are complete ... but at least what group does it belong to?

This is Xyela sp. (Xyelidae)
It is not written where and when it was taken, but it is written about the quality of photos
If MO, then it is most likely Xyela julii, although if the ovipositor is longer than the body, it is X. longula

61-70 - D. New items-Begichevo, Serpukhov district, Moscow region.

I forgot to write, 18.04.2014 MO, Railway, on the light.
Damn, I'm kind of retarded, I didn't even know about the existence of such a family
The ovipositor does not protrude beyond the wings when folded.

First, I would like to write about the importance of camera angles. I would like to see the venation of the wings, the first abdominal segment, and if possible the face.

Help usc determine. At least until Rod. (Ukraine, Vinnytsia region, Mogilev-Podilsky. I found several such individuals at my home on 18.04.2014. )

Tell me what kind of paper wasp belongs to from the magazine Insects and their friends No. 41

Why do you need to know? You can't even say for sure where this "beast" comes from...

So I wanted to find out where this Wasp is found! Is this species found in Russia?

6.12.2014, Kiev, in the ground brought from the forest (oak, pine), 2.2 mm.
In "green", Leptothorax is obtained, with the type of problem.
Tell me who it looks like.

Please identify the ants:
South of the Penza region, the edge of an oak forest, large black woodworm ants at the base of an oak on August 13, 2011 (photos # 3333 and 4444) and in the same place a steppe slope, nest in the soil on May 8, 2012 (two photos: 5555 and 6666)

and there on June 7 2013 at the forest edge ants at the caterpillar:

Many thanks to colleagues!!! But who knew that their collections and measurements would be needed... Just now I'm writing a message about the discovery of the steppe runner-Cataglyphis aenescens Nylander, 1849 in the Penza region, so I thought, what species of ants live next to it???

There is an article like this for the Penza Region's regions:

He doesn't have this article

I usually consult with V. A. Zryanin on ants, but now he seems to have left again, does not answer.
I use this article on ants of the Volga region (although the map there is strange-ah to the Kirov region):
Zryanin V. A., Zryanina T. A. New data on the fauna of ants (Hymenoptera, Formicidae) Middle Volga region. / Uspekhi sovremennoi biologii [Uspekhi sovremennoi biologii], Moscow, 2007, vol. 127, no. 2, pp. 226-240.

In the Penza region, ants have not been practically studied so far.

I ask for help in determining.
