Identification of Hymenoptera (wasps, bees, ants)

I don't know much about foreign ants. Therefore, do not judge strictly and if no one answers exactly, you can guess a little. Small ones are very similar in appearance to ants of the genus Monomorium, but then the size should be 2.5 - 3 mm. If they are larger, they may be from the Pheidole genus.
Large-of course Camponotus. There is no doubt about it. I don't know what kind. It is similar in appearance to Camponotus maculatus. All this is just speculation. If someone knows for sure-write.

This is probably the best site on ants in the world. As far as I know, Bolton oversees it. Some sections are dedicated to other specialists. But there I did not find any qualifiers (although they are found in some works of various authors, links to which are indicated on the site. if you search). And there are photos of not all types of ants. And how to determine just from photos without knowing the characteristics that determine the type? Based on the "similar-dissimilar" principle? Try using this principle to identify formics or mirmics. Especially if there are not all types of photos. The site is undoubtedly the best in the world for ants, but I wouldn't recommend using it to identify species. It's easy to make mistakes. Moreover, photos are presented of collectible specimens that have lost their original color due to time and conditions and can also be confusing.

Hello! A bee has just emerged from the leaf cutter's cocoon on 01/04/2015. The cocoons had been in a test tube since autumn. Please define it. Thanks!

Coelioxys sp.

Thank you very much! Is it a female or a male? Will she be able to live in captivity for some time (honey, water)-it's cold to release.

Krasnoyarsk,
9 mm. The mandibles are three-pronged at the apex, with a small denticle on the inner side. the pygidal field is broadly triangular. Hind legs with strong spines
Crossocerus dimidiatus?

Good afternoon, gentlemen!
Today I found my old photos of the pages of the insect detector. I took these photos in the late 70s. I was re-shooting the pages of some determinant in the Scientific Pedagogical Library named after him. Ushinsky district. I remember that the book was large and very thick. I only retook the pages on ants and wasps. Sameystvo Vespidae goes under number 28 on page 733. I can try to post some pages, but the quality will probably be even worse than in the photos.
This is not the index of insects of the European part of the USSR (Green) - the text does not match. And not the Plavilshchikov determinant. No one knows what that determinant was?

This is a 1948 green car.
You don't need to upload it.

Tell me, what kind of riders? I can't tell you the dimensions. I only managed to capture it with my camera...
