Identification of beetles (Coleoptera)

I picked up Eupithecia denotata caterpillars in Lichens whose caterpillars develop on the bell, and at home I found a passenger.
M. O., Lichens 21.08.2016. on the bell (possibly on Campanula trachelium)

yes, a female Cleopomiarus graminis, a great lover of bluebells

Surroundings of Kirovo-Chepetsk, Kirov region. September 1st.
On the bittersweet nightshade-Solanum dulcamara (Solanaceae).
Aphthona lutescens? Or maybe A. nigriceps?

June, Saratov region

Rhizotrogus solstitialis subspecies, see Catalog of the Palearctic

Friends! Help me identify the beetles collected in Georgia, in the Ambrolauri region, as I understand it is some kind of langriid?

And who is "langriida"? If it is furry (Lagriidae), then it is not. And not Languriidae (lizard beetles). According to its general habit, it is an abscess (Meloidae), of the type Lytta-Teratolytta. But I don't really see the signs. If it were possible to cut out the beetle itself from the source code and show it with a higher resolution, at least the whiskers and paws, it would be possible to say more precisely. Or shoot the collected material. The larvae are leaf beetles, but I don't know which ones.

For me, this is some kind of narrow wing (sem. Oedemeridae)... Judging by the size of leaf beetle larvae, the beetle is small - no more than 10 mm

on the nightshade, it seems, aftons do not fatten maybe something grew nearby?
is the beetle assembled? the campaign is a female longitharsus, and this is a lost cause; (

And by whom, then, is it gnawed?

Hello! Please help me with the definition:

1. 30.06.2016 p. Anadoly Khotynsky district, Chernivtsi region.

Help me identify the nutcracker.
Georgia, Svaneti, Mestia settlement, alpine meadows, about 2400 m above sea level, 20.06.2016.

The bug is not assembled.
When searching for afton, I came across information about nightshade... And by whom, then, is it gnawed?
But, since this is Longitarsus, it is not so important anymore

Good evening, everyone.
Here are two beetles. The one on the left is caught in the depths of the Moldavian Codras, under the bark of a lying beech trunk. On the right - Moscow region, Balashikha river Railway.
Moldavian like Thanasimus formicarius, but it seems only on conifers. We don't even have coniferous forests. And from the place where it was caught, even coniferous plantings for many kilometers are not present. Question: Can formicarius live in the depths of a pure deciduous forest?
And then on the right - Thanasimus femoralis?

China, Port Arthur (Liushun), late July 2016
