Identification of Hymenoptera (wasps, bees, ants)

Is this Sceliphron destillatorium?
Krasnodar Territory, Arkhipo-Osipovka,
15. VI. 1975, leg. E. Berlov. 23.5 mm.

And this is Stizus bipunctatus?
Crimea, Simferopol 15. VIII. 1971, leg E. Berlov.
Body length 15 mm.

Oxybelus is about 7 mm. The mandibles are black. The top of the forehead is in raised hairs, the bottom of the forehead in rather thick pressed ones. The light pattern is white and yellow. On 1-2 abdominal tergites, there are two underdeveloped spots. The lateral scales of the posterior meschytium are not bifurcated, simple. The thighs of all the legs are black. I believe this is O. uniglumis male

Good evening. I ask for knowledge. Filmed in Mineralnye Vody. Sincerely, Andreas.

John-ST, you've got 1 and 2 mixed up. Very poor quality of photos, but if the darkening in the proximal part of the wings of the wings is not my imagination, then on the first two - the uterus Lasius brunneus.

2. Is this Halictus?

Changed it.
Yes, the base of the wings is darkened.

Then what is your version?

I don't know. I didn't see any of them. But I think that the children of this beast will be yellow. This is hinted at by yellowish legs and the bottom of the abdomen. At least in the photo, it seems so. Probably someone from Chthonolasius, but some of the ones I didn't come across.

With such a big belly and a chest wider than your head? Not possible. I just came across exactly the same (as far as you can compare from a mediocre photo) uterus Lasius brunneus. They live in rotten trees, winged workers sometimes drag up or down the trunk, then you can admire them in all their glory. But I've never been on a plane before.

Can someone tell me Camponotus at least up to the group of species

Is it possible to identify these sphexes from this photo?
And what were they doing in such a crowd on the flower?
21.06.2016
Volgograd region, Nizhne-Chirskaya St.
20: 30 dusk was approaching, but it didn't look like they were going to "sleep".
As I understand it, the larger ones with red legs are females, the smaller ones with black legs are males.

No, it's [Crabronidae, Pemphredoninae].
Up to the type of data is not enough.

There is also such a photo
I met on a large old pine tree near a sand quarry.

5 mm. The mandibles at the apex are bicuspid. Dark brown, dark red towards the top. Platypus at the top with slightly outlined three bumps, without denticles on the sides. The forehead is very thick and finely dotted. Hairs on the crown of the head och. Short. Pronotum with yellow spots. Midspine is also densely punctured, on the base with short longitudinal ribs. The shield is also punted. The median field of the propodeum is shiny, bounded by a clear deep groove behind, with oblique wrinkles on the sides. Lower legs with yellow spots. The pygidial field is shiny in large rounded dots. Very similar to Crossocerus uchidai.
It differs from emarginatus in a more developed yellow pattern. From elongatulus by the color of the mandibles.

Happy New Year and Happy New Year to all of you!
