Identification of beetles (Coleoptera)

With them, it can be difficult to take photos from the same angle. A number of species with red elytra differ mainly in the details of the pronotum structure and, partly, in size. Yours, with a high probability, A. sanguineus-should be large (12-17mm).

And what is this unusual beetle, today on the old linden tree photographed, size approx. 8mm, but aggressive at the same time, and not shy at all

Surroundings of Kirovo-Chepetsk, Kirov region. May 25.

Is it possible to identify a beetle at least to the genus from such an indecent angle:

I was sitting in the cell of a polysta wasp's nest, but I couldn't get it without damaging the nest. Yesterday, Donetsk, steppe slope of Balki.

Good afternoon!
I ask for help in determining.
The beetles were collected in early May 2016 in the Ramenskoye district of the Moscow region

1 Calopus serraticornis?

2. Platystomos albinus?

3. Platyrhinus resinosus?

Thanks!
Now I will know what you need to shoot in more detail from similar people. In the meantime, there are only such on this nutcracker:


Found more key by ampedus.
Ampedus sanguineus there looks like this:


Mine seems to be similar. Yes, and the size was more than 10 mm. If there are no objections, then I will sign it.

hello everyone!
Moscow, May 02-
please help me identify the black beetle and the small ones around it.

These are not beetles, but aphids.

Harpalus. According to the photo, I would have blurted out H. rubripes, the pubescence looks like H. affinis, but everything is green for me. Check it out.

Thank you, but the black one?
and whether aphids are accurate, they are larger than 2-2. 5 mm and move at a decent speed.

in parts, can anyone help determine trogoderma? Judging by the parameters and the bridge, there is something between inclusum and versicolor. Unfortunately, other parts of the body were not preserved. Uzbekistan, in barberry.

Diakuyu-thank you, I already began to doubt that Harpalus. But these are neither rubripes nor affinis. These species are the most common and easily recognized here. Smaragdinus is not even closer, but smaragdinus, but the increased fur on the back is embarrassing. Yes, and purely externally, too, is not the same. Strange, the view is most likely some ordinary Central European, but I can't find anything similar.

Please help me identify the nutcracker. Saint Petersburg, 29.05.2016

Dear experts, please tell me in which family to look for the definition of this beetle? If it's a bug at all...the length from the tips of the whiskers to the tips of the paws is approximately 3 cm.

Shot in Cat Tien National Park, Vietnam. 4.6.2016, arrived at the light.

Good day to all times of the day, check the definition if possible
