Hello dear colleagues. The beginning of the season coincided with my birthday. - When planting violets from the front garden, I found this bug in the ground: - sorry, please for the quality - shooting with a whale lens is a thankless task. I don't even know what kind of family it is... - kozheed hardly?
- 4 millimeters exactly.

I may be wrong and the place of capture is unusual for him, but it is very similar to the soiled Helophorus (Helophoridae).

"I was just carelessly surprised by how different it is from the Aquarius

. - And only after I looked at photos of this genus on the Internet, and then looked at the Web in Russian, I realized that HELOPHORIDAE is a family of "Wrinkles"!, which I had never encountered before.

- Well , - and about the definition of the species, of course, it's a shame to dream of such a photo and without keys and binoculars. Especially since the devils are so small and so similar to each other!

Yes, and if you have keys, binoculars and a whole series of wrinkles in your hands, in most cases it is not much easier to determine them

Please confirm or deny that this is Poecilus Versicolor.
The number of bristles on the inner side of the thigh is 5.

The bristles should be counted (and also compared in thickness, length, and color) on the shins, not on the thighs!

Cool?

About the "coolness" of cupreus and versicolor, I already answered above.

Sorry, I made a mistake in the text out of joy that I understood them.
Thank you.
I think I'll buy a pair of binoculars by the fall and distract you less on trivial matters,
but now, with your permission, I'll contact you. I want to sort out my beetles by species before the season starts.

Dmitry, have you received my photos of leaf eaters? what can the thread tell from them?

14.03.2010 10:12, scarit

Yes, Agonum. I got a photo, I'll definitely take a look! Just a bunch of things to do at work overcame

I ask dear experts for help in identifying these beetles:

Can it be Harpalus (Epiharpalus) affinis (Schrank, 1781) (except #5 and#6)?

Thanks

14.03.2010 12:54, Алексей Сажнев

Options 3:

Harpalus (s. str.) affinis Schrank, 1781-the first two, I think just it
Harpalus (s. str.) distinguendus (Duftschmid, 1812) - maybe all the others

and maybe

Harpalus (s. str.) smaragdinus Duftschmid, 1812

- in affinis, the outer spaces of the elytra are dotted, in the other two they are bare and smooth - separate the affinis first, and then you can deal with distinguendus and smaragdinus, the latter is unlikely, probably in my opinion. Athenis is also often brighter and has lighter legs

Dear Alexey Sazhnev,
I Am Reporting.

All 6 have a dotted line in the gap of the outer furrow of the elytra(if I understood correctly).
It turns out that all 6 Harpalus (s. str.) affinis Schrank, 1781.
I'll go fix the completed material at the GG.

thank you very much!

14.03.2010 14:25, Sugercete

What a fool

I confused the dotted line with the large pores of the marginal gap.
Apologize.
So, it turned out that all but # 5 have a dotted line!

No. 5 has no dotted lines(the surface is as smooth as a samovar), and mustaches! 2 and 3 segments at the base are dark + legs and underparts are pitch-black.
It turns out that # 5 psittaceus Geoff for YY.

Can this be the case?
What is this H. psittaceus Geoff now called in YY?

Thanks for the answer and apologies again for the dotted line

14.03.2010 14:33, Алексей Сажнев

Yes, it can - psittaceus is a synonym for distinguendus

Please confirm / deny all three Harpalus rufipes (De Geer, 1774)
It is doubtful that No. 1 has a red overhanging border of the prsp, while the other two have a black border.
All three of them have elytra with thick short hairs(this is almost not visible on the scan).
