Can't it be Trichiosoma?
The clippings are covered with a white membrane, clearly visible in the previous photo, invisible, and the belly seems to me too hairy

Wasp-shaped sawfly ?
Moscow region, Ramenskiy district, Khripan, glade under power lines, about 10 mm.

Dear comrade gumenuk, I apologize for the hastily incorrect "definition" of Really a sawfly from Trichiosoma
PS: to the above said answer. Thanks for fixing it again. All I'm writing is assumptions (possibly erroneous) two.

Upper - Clover tenthredo (Tenthredo schaefferi)?
And the lower one?

A hundred bumblebees?

Upper - Clover tenthredo (Tenthredo schaefferi)?
And the lower one?

I think they both have the same image

well, yes, and what is surprising here, bumblebees are also bees, only fat

I can tell them apart, but sometimes I also want to determine the view, at least of what is in the image next to the honeycomb

"All I write is speculation (possibly erroneous)"
At the same time, you make them out as true statements, which mislead others.

Upper - Clover tenthredo (Tenthredo schaefferi)?
And the lower one?

Most likely, both photos show the same species of the genus Tenthredo, I can't say which one.
Regarding Tenthredo schaefferi: according to the" green "Tenthredo schaefferi is a synonym for Tenthredo arcuata, but there is also a reference that usually the species Tenthredo arcuata is divided into several species, for the ECR of the USSR it is Tenthredo schaefferi, T. notha (perkinsi) and T. arcuata; according to the "fauna" these are three separate species, as they differ in different species. I don't have any information, all these species eat clover.
In general, the membranes are a rather muddy group, so it is impossible to determine the majority of this genus from a photo, especially from one angle , so accept it.

I try to double-check any definition

How, if the images are in the Net, then this is complete nonsense. So, probably, you can detect an error only if you are poked at the white house by an admiral (I'm exaggerating a little, of course). Many insects cannot be identified from photos in nature, not only because many species are similar, but also because the available images simply do not show any systematic features.

Dear John-ST, what makes YOU think that I am CLAIMING, and even TRUE, and how do you formalize assumptions? Kytay eroglyphs

This is Symmorphus I'm leaning towards crassicornis female, though as a variant of murarius (nothing to compare the pits behind the ocelli with). 15-16 mm. Indeed, a longitudinal depression is visible on the first tergite. Behind the eyes are depressions with hairs. The top of the chest is covered with long hairs, just like on the head. The parietal fossa is located close to each other. The sides will break. segments in irregular folds, some raised. The lower legs are mostly yellow. 1st tergite in rough, rather thick dotted line. On the top of 2-3 tergites, the points are rougher than on the rest. There is a roller on the fold of the first tergite, but it doesn't really stand out all the way. There are no yellow spots on the chest, only on the pronotum. The handle of the mustache is yellow-red at the bottom.

Something from Ancistrocerus, I think it is ichneumonideus male, although possibly trifasciatus.
Propodeum leathery, slaboblestyaschiy.9-10 mm. . The 2nd sternite is uniformly convex.The ridges on the basal transverse sulcus are longer in the center than on the sides. The back of the box has no yellow pattern. There are 3 yellow bandages on the abdomen. The bottom of the main part of the mustache is brown. On the ext.on the side of the eyes along the yellow stroke, not reaching the eye socket. It is difficult to understand, the ratio of length and width of the architrave seems square. The dots are quite large, but not deep. Zhg. sawyere from the bottom is almost completely red, darkened in the middle.

According to the DV determinant, I go to the female Ancistrocerus parietinus.. 10-11 mm. The 2nd sternite is uniformly convex. The color of the legs is rusty-red. The flagellum of the mustache is rusty-red on the lower segments and upper 3 parts, the middle parts seem to be completely black. On the tergites there are 4 bandages, on the 5th tergite there is a yellow spot in the middle of the apex, on the last tergite there are also small two spots. On the head there are rather long hairs, the first tergite with raised hairs. At the inner edge of the eyes, there is a single red spot on the platypus.
The platypus is quite wide, tapering to the top, not elongated. Full yellow baldric on the second sternum and with a thin strip on the 3rd with extensions on the sides. The middle and hind legs are light. On the shield and on the sides of the chest there is a small yellow-red spot.
although possible ichneumonides or trifasciatus....

But that's just the way it is - all bees are in the same family Apidae. All old families, subfamilies, and tribes are downgraded by one rank. Take a close look at the most recent work:

Melo G.A.R., R.B. Gonçalves
2005. Higher-level bee classifications (Hymenoptera,Apoidea,Apidae sensu lato). Revista Brasileira de Zoologia, 22 (1): 153–159.
http://www.scielo.br/pdf/rbzool/v22n1/a17v22n1.pdf

I know Gabriel de Melo personally - he is a very serious morphologist and taxonomist, who will not just lay out anything without justification.
But, for obvious reasons, many apidologists are guided not by some cladistic calculations of an unknown Brazilian, but by the opinion of their master - Charles Michener and his system of 2000. What they don't know is that Gabriel did his dissertation at Lawrence under the same C. Michener.
But everything flows - everything changes. Here sphecidologists quite calmly accepted the division of "their" family already into 4 independent ones, so it will be apidologists ' turn. By and large, all bees are the same crabronids, but just with vegetarian children.

Wasps from Germany

More suitable for Coelioxys brevis Eversm male. Caught in the south of the Krasnoyarsk Territory. Minusinsk, Lysukha, sandy slope. 7-8 mm. On the body there are also scales in addition to hairs. Front basins without a spike. 4th sternite of the abdomen without a notch on the top. Question on the color of thorns on the 6th tergite, in general they look black. Flagellum of antennae from the second member. brown from the bottom. The mandibles are brown in the middle. The front of the face is covered with rather thick white hairs. Scales at the lower edge of the eyes with a shiny platform, in front of which is an elevation, in the form of a small clear ridge. On the 6th tergite of white scales at the base there are two white spots, interrupted in the middle.
8 thorns on the 6th tergite, and two on each side on the 5th tergite.
Bandages of white scales on tergites in one row, but sometimes small scales are wedged there, I do not form a complete second row. This is possible ruficaudata...
