Patrobus assimilis ?
10 mm Shore of a forest swamp.

For some reason, I like it better as P. atrorufus (if it is still called that). I don't know if there are shoulder teeth or not. But assimilis is still smaller.

That one, that other - both 8-10 mm.
But atrorufus seems to be wider in the elytra.

But I would like to know how they differ. Are there any solid differences?

10.04.2008 0:34, Fornax13

It seems like atrorufus has a humeral denticle this very one, assimilis doesn't seem to have one. The base of the prsp. before the western corners of the second is slightly sloped. P. assimilis, still a little smaller - 7-9 mm. In P. atrorufus, in my opinion, the ndkr. is wider, thicker and the grooves are weaker than the former.

Although, maybe it's true assimilis - you need to watch it.

rpanin, your patrobus is not atrorufus. The angle of the pronotum is quite different, the elytra are wider in relation to the pronotum. It's not his proportions. I did not find any clear differences, everything is at the level of such nuances. It comes when you view a series of views. My opinion-patrobus australis

And what kind of view is this in general? How is it known? And then, maybe, you should check your own on this score-you never know, what else can there be besides abnormal septentrionis.

What kind of ground beetle? 1.5-2 times less than Carabus violaceus (a trifle in the sense), this week in Moscow.

I personally help myself with a dictionary (although I once learned German), when studying European beetles, it is difficult to do without German.

To Filin: The first two pictures - the family of barbels or woodcutters-Cerambycidae-let our dear experts of the family determine the species (there are enough of them on the forum). The third is the abscess beetle (Lytta vesicatoria L., Meloidae).

Yes, it's all good . But the time ??? Chronically not enough for everything about everything. Especially when you're in your late forties.

The first barbel is a large aspen creaker - Anaerea carcharias (L., 1758).
The second barbel is Phytoecia (Opsilia) coerulescens (Scop., 1763) - I do not know its acceptable Russian name.
Naryvnik (shpanskuyu fly) You already have Mylabris defined above.

Try this, print out that page and label the translation of each word at the top of the line. You can use a dictionary, or a dictionary on the Internet, or even there are translators of the whole text. Print out the second page from that determinant and doing the same you will notice that the words are repeated and there are not so many of them. On the third page, you will rarely use the dictionary. Try. And it will work.

Hooray, it's working!
okoyem is from the genus of Pentondon, and not dung
IN-chernotelka very interesting, especially if you consider the correctness of the given size. Then it's definitely not Penthicus dilectans, it's almost half the size. I think it's not Penthicus at all. Wait, I'll look in the boxs

I'd say it's bidens. But I feel Nimrod coming and putting everyone in their place, saying it's an idiota of some form.. But for now let it be Bidens

Sorry, I misled you, the size is 1cm. I think Mylabris is right this is Penthicus dilectans Fald.

Thank you very much! Tell me how to distinguish the gender of these beetles.

First, I confirm that I do not have any specimens of Penthicus dilectans more than 10 mm long.

What kind of sawyere? Place of capture of several individuals-Vladikavkaz June 2007 on the Willow tree. Maybe musky, but why is the collar red?

13.04.2008 14:45, Vabrus

A. moschata may have red pronotum spots. So apparently it is.

13.04.2008 15:20, metallman.92

It's supposed to have something to do with a dragonfly. Place of capture: Moscow.Area, the former village of Troitskoye, near the place of capture there are 2 small artificial ponds. August/September 2007

Posdskajite please name, and what stage of development.

13.04.2008 15:48, Vabrus

This is the nymph (i.e. larva) of a dragonfly. Possibly Cordullidae or Gomphidae. Someone will probably write a thread more precisely.

EDUAD :
It looks like musky, just a different subspecies - many subspecies of musky have a red pronotum. But what exactly is the subspecies say KDG or Cerambix

13.04.2008 16:12, metallman.92

does anyone know what attracts these barbels to the Willows? And why is there some white foam on the trees where they live? I thought it was strange)
