Identification of beetles (Coleoptera)

Here on nettles-easily. But still, he's probably a little different.

Help with the definition. Samara beetle, size 1.3-1.5 cm

Anoplotrupes stercorosus (Hartm. in Scriba, 1791)

Thanks for the definition, but still why not Geotrupes stercorarius. It seems to be more similar to the punctuation of the pronotum?????

Well, maybe a little. Here is a photo from the morning walk. These are ligustes.

And what is he sitting on? If not a staged photo, of course.

Chrysolina hyperici (Forster, 1771) ?

It looks like it, it looks like it! This is from this group of species for sure! But it's not easy to bring up the type and material, and even the photo is unrealistic.

What kind of floater? I caught 32 mm
in a puddle today.

What is Chrysolina sp. I agree, but I would like to get to the view, if possible, are there really a lot of different purple colors?

What about Chrysolina geminata, for example?

On St. John's wort, I caught several types of Chrysolina. It is also difficult to say anything about the color scheme. Both Ch. hyperici and, for example, Ch. variants are so diverse in color...
About Ch. geminata: yes, I've only seen this color, but hyperici differs from geminata by having double rows of dots. The photo is very similar. However, I'm just learning about leaf beetles - I might be wrong

Bottom photo would be...

All right, we'll run away in the evening.
All the views are so similar, according to this link.

That's why you need a photo from below - the shape of the processes of the rear basins can be distinguished quite confidently.

Nilson-Caught both of them. 2nd most likely sahlbergi, no options. 1st on soluta, which I saw is not very similar-too wide bandages, and in my opinion it does not go so far to the east, though... for the solute, a reliable sign that distinguishes it from the hybrid group is the presence on the shoulders of the elytra of a bunch of upturned hairs, clearly visible even at a small magnification. A larger and more massive mount. Do you have any hairs?

Thanks!
The fact of the matter is that there are hairs. They seem to be slightly visible in the photo and are just confusing, since the soluta along Kryzhanovsky goes east to the Don - You are right. Here.

It goes to the Volga River, but it is not known from the left bank. The hairs are really noticeable - very interesting. But, once again, it doesn't look like a typical soluta. In what biotope is it caught? For solyuta, these are sandy manes in pine forests...
