Identification of beetles (Coleoptera)

female stag beetle Lucanus cervus

And what kind of crunch is this? North of the Rostov region, 06.2010.

Tell me with a mustache. It seems to me that this is Trichoferus campestris Fald, I have never seen this genus, so I may be wrong. It was found on blanks for pallets, most likely coniferous. In the vicinity of Krasnoyarsk.

Can you tell me who it will be? Caught in the vicinity of Krasnoyarsk mid July 2010

Dear colleagues, I am not very good at nutcrackers. Can someone suggest it? Length 11.5 mm, forehead completely bordered, flat, all legs without lobes. It is caught in the North-eastern Caspian region.

I also suffered with this animal for a long time. This is the genus Aeoloides (M. b. grisescens even) - there are not many of them, there is a revision on Zina.

Saperda perforata, worn

Hello friends. Please write me the name of this "scarita"...
Caught the day before yesterday morning on the curb of the central Avenue in the city. Next to the lawn is watered grass.
The length is 7 mm. The paw on the right front leg was missing. Crawls slowly. He scared me with his jaws.

Help to understand the types of small ground beetles.
Kharkiv, night from 16 to 17 and from 17 to 18 Jul on the light
I lay down, height and weight need to write?

I have a question for you out of curiosity, but what is a separate genus, not a subgenus?

I was wrong. Donacia cinerea? Herbst 1784
Probably should be:
Subfamily Donaciinae
Genus Donacia
Species cinerea

Hello, dear friends. Please tell me.
1 - Donacia dentata? Length 8 mm. The color could have changed a little while I drove home, it was dried out from the heat.
2 - Donaciella cinerea? Length 10 mm
Nizhny Novgorod region, Dzerzhinsk, Seymovsky zaton

  
2. Some strange cinerea. My legs are definitely completely different..... And what is it assembled on? We have cinerea found exclusively on cattails

   Tetropium fuscum (Fabricius, 1787)

1. My Donacia dentata is a little different in color, but in general it seems similar.
What are you caught doing? The photos are "staged", aren't they?
In my collections, all representatives of this species are collected exclusively on arrowhead. And I didn't collect any other types on arrowhead.

Not surprising. Because it is D. tomentosa that lives on Butomus.

Tell me what kind of elephant it is.
Floodplain meadow. I flew in on my own.
