2amara-very similar to Agabus guttatus (its size is 7-9 mm) A. biguttatus is larger (11 -13 mm) and with obvious striation of the elytra. Both live in springs and cold ponds with spring outlets

Thank you. These, 10 pieces, live in a concrete ring filled from the bottom of the key with continuously changing running water. The top is covered with a lid and there is little that gets on top, occasionally a small ground beetle or even less often a frog will fall off. I wonder what they eat there. We need to take a closer look.

Please help me if possible.

3. Another Pterostichus sp. Very similar to Pterostichus (Feronidius) melas (Creutzer, 1799), but I have my doubts.

Esdi is defined by European keys as melas, the Pterostichus (Feronidius) fornicatus. A common animal in the Caucasus.

Thanks!

To Ripper: Unfortunately only one got caught

To Fornax13: Aha, I use European keys to access melas

All of them?

25.09.2009 18:31, vasiliy-feoktistov

All. Sash, she's the only one with spots on the end of her belly. Can be: red, pink, yellow, white (varies greatly in color).

Does Buprestis rustica have any spots?

Does Buprestis rustica have any spots?

No. Yes, and it is wider and quite rare.

Ahh! So that's what it's all about! Thanks!

And these I identified as
Galeruca tanaceti female
Saperda carcharias female
Upis ceramboides-I do not know the gender.

Right?
And what is the gender of Upis ceramboides?

In continuation of the zhuzhelyat theme-2 pterostikha from Saratov.
I identified the first one as P. oblongopunctatus
, but there are problems with the second one, Poecilus lepidus comes out, but we don't have it listed.

1 - yes, for sure...

Looks like. And the fact that it is not specified - so not at all still indicated

25.09.2009 20:39, Mantispid

Well, in general, thank you very much))) now it is specified))))
in principle, I defined it a long time ago, I thought that I was mistaken, it never bothers to double
-check p. s. there is the first female, and the second male?

25.09.2009 20:40, Victor Titov

but with the second problem, Poecilus lepidus comes out, but we do not have it specified.

In my opinion, so male Poecilus lepidus.

26.09.2009 17:30, Liparus

Alas, this is one of those times when I don't remember what he was sitting on.
I took more photos, maybe they will help?

I disagree with those who identified as B. Betulae
the punctuation of the elytra is different, the size is suitable for both, but birch trees are often larger,and blue forms in birch trees are often found in aspen populi I did not catch the blue form,there are black and red ones.the other legs are thicker in relation to the body and black, from the bottom the beetle is also dark and not shiny (if compared with the elytra)..

male, rather Byctiscus populi ... ... top blue, bottom blue-blackb legs black ab. nigripes (Faust)

Dear Liparus, that's why I decided that this is a birch beetle - the general habit - birch is clearly wider and stockier than poplar - this beetle is just like that. Poplar is not only smaller, but also slimmer, especially in the case of the male.

Well, I will not argue, of course, maybe birch, but I think that aspen

P. lepidus is not very rare even in the Volgograd region up to the south of Volgograd (along the floodplain), and even in the Saratov region it was not indicated only "due to an oversight".
To the question about the field. Males in most ground beetle genera are defined elementary-forelegs with extended segments and a hairy sole, like in your specimen.

the paws of this one are shiny and the paw itself is shiny,and in the photo of Sungaya, the paw is black almost brown in color

now compare the undergarments http://www.biolib.cz/en/image/id82475/ and what's in the topic.similar?

The glitter of the legs or its absence in the Sungaya photo is the effect of lighting when shooting. In addition, do not forget that the top and bottom of betulae are always monochrome. I believe that this is still B. betulae.

That's it, in the photo Sungaya top and bottom are multi-colored
here from the bottom and on the legs of the villi http://www.biolib.cz/en/image/id82475/ and in the photo in the subject they are not, how do you think they were erased? at the expense of lighting here I agree

Due to the fact that the definition of this bug threatens to grow to the level of a separate topic, you will have to contact Legalov

There are only 2 species of this genus in M. O. and B. populi never has such a color (as in the picture).

To Sungaya:
please take a close-up shot of the head of this bictiskus, but we will remove the question already

Or on a beetle see for yourself: betula has a slight indentation between the eyes, rough elongated points, and an almost wrinkled sculpture.
Populi has a sharp elongated fossa between the eyes, small round dots.

Dear Fornax13, and on the previous page in the post Sungaya from 25.09.2009 13: 18 do not look?

It seems that the head can be seen better there...

it has, it also has a black and dark red one (it's written in my book)

I'll take his head off in the morning, okay?

as big as I can get.
Otherwise, if I go after the bug now, I'll have to wake up two people, they're sleeping with my bug in the other room

It will be difficult for me to explain the reason

Well that's what I was saying:hairs in B. betulae (the entire underside with the paws is hairy), in B. populi, as in the Sungaya pictures, there are no hairs either on the paws or on the lower part of the body.
Well, we are waiting for the head, I want to figure it out, but I am 98% sure that populi
