Identification of beetles (Coleoptera)

What's the size?
Of course, Sazhnev is completely right-Labidostomis is almost impossible to determine from the photo. But given the fact that the Moscow region, that there are no shoulder spots ... If the size is about 8-9 mm, then 60 percent - Labidostomis tridentata. Only here on ivan-tea, apparently, accidentally sat.

Yes, the size is approximately the same (I only caught these at home). And oddly enough, I collect it from ivan-tea (apparently it catches my eye more)

And on a shrubby willow, what kind do you not know?

Mine probably is (where I collected it-there are plenty of willows), but the region?

In the willows not one can be found. They're omnivorous. This is the same Labidostomis tridentata, and L. lepida, and L. cyanicornis, and L. pallidipennis... We need to catch males and identify them.

It's pretty common (I keep bumping into it).

Is the beetle a good one?

Which one of the above ones, as possible on willow? Arthur, you can identify your own people.

Not O. Olens, then?Ocypus curtipennis?
Crimea, Bakhchisarai district, 100-400 m, 07 August 2009, under
the stones.:31mm (with mandibles)
about 5 dead people were found under the rocks ,all scattered

Please tell me, what is this ground beetle? Place of capture - Krasnaya Polyana, height - 800 m.

some Aphaonus sp., up to a species, is likely to be difficult. But all afaonuses are wildly cool and rare ))

Actually, it also looks like O. tenebricosus. Ocypus with a guarantee on genitals is necessary. In general, Arthur, unsubscribe" in the personal account " stierlyz, he will soon figure it out.

Please tell me. Correctly-whether leaf beetles are identified.
1) Cryptocephalus cordiger? - 07.06.1997 on a willow tree. L=6mm.
2) Chrysolina marginata?- 15.09.2009 on a field road. L=8mm.
Both beetles are from here: M. O. Balashikha district, Zheleznodorozhny district.

1) Something on my monitor color skrytnoglav distorted. If the lower legs and 1-2 segments of the legs are red, then Cryptocephalus cordiger.
2) Yes, Chrysolina marginata marginata (Linnaeus, 1758). Only the size (8 mm) is slightly too big. Didn't get measured?

Yes, red hair, but only on the front legs.
2) It is possible and measured (offhand, with a ruler)- most likely it is (the limbata color is black and the border goes to the leading edge of the elytra), but we seem to have only 2 types of similar ones?

This is a male Stenurella sp. Before the view is allowed? The abdomen is not visible

Here the color of the abdomen is important here (male)! Offhand: S. bifasciata?

And apart from the abdomen in any way?

On the male-no way.

And apart from the abdomen in any way?

If the abdomen is black, it is S. melanura, and if it is red, it is S. melanura. bifasciata (only 2 species in the Moscow region I know).

Well, if you mean "edged", then, counting marginata, not 2, but at least 3:
1) Chrysolina sanguinolenta
2) Chrysolina gypsophilae
These two species are black, with a red (orange) border of the elytra. They are "bred" by the punctuation of the elytra (in gypsophilae it is larger, the spaces between the dots are convex, wrinkled, and in sanguinolenta it is smaller and the gaps are flat, smooth) and along the inner edge of the border (in gypsophilae it usually goes beyond the second row of dots from the edge of the elytra and is jagged, uneven, and in sanguinolenta it only reaches second row of dots and smooth). According to my observations, sanguinolenta is more common in the Yaroslavl region than gypsophilae.
3) Chrysolina marginata - it is completely different from the first two species: it is smaller, and "progoniste" (the body shape is more elongated, almost parallel-equilateral), and the color is dark bronze. In short, not at all like sanguinolenta and gypsophilae!
As for Chrysolina limbata, I personally did not find it in the Yaroslavl region. Like in Moscow , I don't know.

Thank you, Victor, about limbata. Here, please correct it (if possible from the photo). L=6,5mm.

It would be nice to look at the profile (side edge of the border), and so-Chrysolina gypsophilae.

Now I'll take a picture and upload it.

Here it is on the side.

I think Chrysolina gypsophilae (the border clearly goes beyond the 2nd row of points).

Please tell me, what is this ground beetle? Place of capture - Krasnaya Polyana, height - 800 m.

Given the location of the capture, I would say. that it is Aphaonus starckianus Rtt., but it is also possible that it is A. cylindriformis Rtt. (the photos are useless!).
The label is cool - "Adler, Krasnaya Polyana". Well, what kind of Adler is there!?

I think Chrysolina gypsophilae (the border clearly goes beyond the 2nd row of points).

Well, there is also a dotted line, as you correctly noticed, not at all like limbata!

Thanks for the tip. Species, as I understand it, are genital? Do you happen to have any keys on them?"
Well, the label.... I myself understand that this is nonsense, but I got a bug with such a label....

That's right, it was based on the dotted line that I initially concluded that this is gypsophilae, and not sanguinolenta. And what is not limbata-you can immediately see, it has a border in general right up to the shield reaches-rounded off.

As for Chrysolina limbata, I personally did not find it in the Yaroslavl region. Like in Moscow , I don't know.

And I found it in the Yaroslavl region and repeatedly

And I found it in the Yaroslavl region and repeatedly

That's nice! So, we can assume that we have 4 "edged" species of the Chrysolina genus:
1) Chrysolina sanguinolenta
2) Chrysolina gypsophilae
3) Chrysolina limbata
4) Chrysolina marginata.

Please dispel your doubts. Is it Hygrotus quinquelineatus ? A single specimen was collected in the lake together with H. inaequalis and H. versicolor. The shape and size are closer to the latter. Samara region.

Judging by the uneven punctuality (different point sizes) of the elytra, it may be Hygrotus quinquelineatus (Zetterstedt, 1828). True, I only saw the drawings and read the theses-antitheses in the determinants, I didn't hold any copies myself.

Yes, the signs seem to match. But the sample was dominated by versicolor, and perhaps this is its "deviation". And what is the probability of finding three similar species in one clump of grass?

I think Chrysolina gypsophilae (the border clearly goes beyond the 2nd row of points).

Something too small for gypsophilae

Size!?
It is clearly larger than the little ones from the next post, and it is removed so that the grooves are not visible at all. Judging by the location of the find - from Saprinus, which lives in pigeon nests in populated areas. Here it was correctly noticed-rather S. tenuistrius, but this is purely speculative - you can't even determine the genus in the photo.

And just the first two pictures reminded me of a representative of the genus Chalcionellus.

That's nice! So, we can assume that we have 4 "edged" species of the Chrysolina genus:
1) Chrysolina sanguinolenta
2) Chrysolina gypsophilae
3) Chrysolina limbata
4) Chrysolina marginata.

The 5th species that we also have is Chrysolina analis. So the border types are still 5

The 5th species that we also have is Chrysolina analis. So there are still 5 edged types

Guys, so in my case: Who is it? Chrysolina gypsophilae all the same?

2vasiliy-feoktistov Probably still Chrysolina sanguinolenta. In Chrysolina gypsophilae, the punctuation of the elytra is VERY rough (even wrinkled) and about a centimeter in size.

Can you help me with this tiny one (3-4 mm)? And then even with the family I find it difficult Moscow, July, flew to the light
