Identification of beetles (Coleoptera)

Please help me identify it. Found in y . Khotyn (Ukraine)

Today I found in the river on a piece of styrofoam more than a hundred different beetles. If possible, please tell me their names. Gathering place-north of the Omsk region, Bolshoy Aev River. Dimensions: 1-about 7-8 mm. 2 - left 6 mm, right - 8 mm. The right one has only red paws, the left one has the whole body. 3-about 8 mm. 4-about 5 mm. 5-7-8 mm. 6-about 5 mm. 7-about 10 mm. 8-7 mm. 9 - 7-8 mm. 10-Chrysolina polita? 11- Chrysolina sturmi? 13- Chrysolina sanguinolenta? 12 - about 15 mm.

But pricking beetles in the pronotum, and even with a stationery pin, is not the case.

Outskirts of St. Petersburg, today. Size 9 mm, brown bottom.

  Gyrinus distinctus?

Most likely, yes. And what are the dimensions of this spinner?

about 10 mm

Hello, I can't identify the instance, at first I thought it was soft, but I can't find it in any atlas or on the Internet. (Caught in the Far East).

The last pair, in my opinion, are granulates. But I doubt it.

Gyrinus distinctus?

I think it's Gyrinus paykulii. The body shape is characteristic and the shape of gonocoxites is similar.

Today, under the bark of a half-matted birch, I found two nutcrackers, different in my opinion by species. Please help me figure it out. One was identified as Ampedus pomonae (its size is about 18 mm). The second one is 11 mm in size and differs in color from the first one. North of the Omsk region, forest zone.

Good day, help

I will assume that in the fourth photo from the left Harpalus rufipes
In the first photo granulatus is only the smallest (second from the right), the rest are cancellatus
A gold leaf Anthaxia sp.
It is unlikely that someone will say more specifically: it is dark and it is not clear where the beetles come from

In the second photo from left to right: Pterostichus melanarius, Pterostichus niger, Pterostichus melanarius.
In the third photo, Amara sp.
In the fourth photo: from left to right: Harpalus (Pseudoophonus) rufipes, Amara (Curtonotus) aulica.
On the fifth and sixth - Anthaxia quadripunctata.

Pca
here's more if possible
