Click beetles (Elateridae)

Beetles of the family Elateridae (Nutcrackers) have an elongated body, their prothorax is articulated with the rest of the body very mobile, the pronotum has characteristic elongated and pointed posterior lateral angles, the formula of the legs is 5-5-5 (all legs are five - jointed).
Larvae of beetles with a hard thin body are called wireworms, usually live in the ground and often harm underground parts of plants.
A distinctive feature of representatives of this family is the presence of a characteristic jumping organ (photo attached). The prothorax carries a backward protrusion between the farthest basins, resting against a notch on the mid-thorax. These beetles usually have rather short legs and, once on their backs, they can only roll over with the help of such a jumping device - by sharply bending the farts down, when the ledge jumps off the notch on the farts, which creates a push and is accompanied by a click.
The development of "nutcrackers" is slow - 3-5 years.

I decided today to support this forgotten topic with views of the Moscow region.
Apparently, it was forgotten because they are quite difficult to define (I have a lot of undefined ones myself).
And in my opinion, these are quite interesting beetles.
3 species of the genus Ampedus:
1) Ampedus sanguineus Linnaeus, 1758. 03.05.1996 Moscow region, Balashikha district, near Kupavna station, under the spruce bark.
2) Ampedus sanguinolentus Schrank, 1776. 13.06.1999 Moscow region, Balashikha district, near the village of Poltevo, on the umbrella.
3) Ampedus balteatus Linnaeus, 1758. 18.05.2005 Moscow region, Lyuberetsky district, Torbeevo village, on birch tinder.

Yes, on what it just does not come across! Only that it is painfully matte? Was the picture processed like this in the store?

Please help me figure it out (I'll fix the post).

Athous haemorrhoidalis. By the way, if the founder of the theme doesn't mind, its name should be corrected by removing (Elater Balteatus, Ctenicera pectinicornis and Agriotes lineatus).
