Hello dear ones. Please write me the name of this "flour crunch"... In general, we have them (similar to each other) are both black and burgundy... I first thought (since it's not black) that it had recently hatched from a pupa, but judging by the disability of the antennae... - the instance is not new-born...

in my opinion Tenebrio molitor

T. molitor is very often brown, and I would advise this beetle to check for T. obscurus (it should have a pronotum with a roller at the base).
P.S. T. molitor (one hundred percent) I previously posted in chernotelki.

what kind of stars stick out of it?

I will quote one work:

"At the junctions of the breast segments, membranous tissues can protrude under the pressure of hemolymph into peculiar bubbles of yellow, orange or red color. It is quite possible that the bright bubbles imitate drops of poisonous hemolymph, which is released in some beetles: ladybirds, leaf beetles, abscesses. Their blood is acrid, and not every predator will eat such" inedible "prey"

At first I thought it was Platynus assimilis. Now I doubt it. The beetle is smaller and more persistent. Moscow, Terletsky Forest Park.
I want to add it... If you look at the light, then on the back you can see barely noticeable dots-dents.

In order not to bother with melanarius-niger, although the external differences are absolutely obvious and I don't understand what the problem is, see the claw segment from below - in melanarius - with bristles, in niger-without.

I ask specialists to help in determining the carabus (calisthenus?) from the low mountains of the Syrdyrinsky Karatau range (South). Kazakhstan). Even up to a subgenus or subspecies...
Length 16-18 mm. The elytra are smooth, without pits or grooves.

I can't even see through the binoculars. Smooth upper mandibles. Maybe you can see important signs from below?.. It can be seen that the penultimate segment of the labial palps is two-lobed...

Hello.... Today at the door of the house on the inflorescence snyti caught this" Anterinus"; but I suspect that this is not a museum, as it differs from it in drawing; and it looks like another species, the name of which I have forgotten. "Explain?"
Sincerely, Andreas (unlike the beetle-still alive).

And I'm closer to A. picturatus from the photo. Maybe because I have it eats more collection smile.gif

Well, seriously - this is picturatus! As much as you can tell from the drawing.

Well no. My varint is closer in my opinion: http://www.zin.ru/Animalia/Coleoptera/rus/antscrab.htm
Here's your: http://www.zin.ru/Animalia/Coleoptera/rus/antpiche.htm
And I think the whole Anthrenus family is such a bastard smile.gif

Compare the drawing in the apical part of the elytra in your own examples with what is proposed for the definition.

Well, yes, but the pronotum?

01.06.2010 22:42, evk

And in the Zinovsky photo, it's a very unusual instance. Picturatus normally (in my material) has a dark prsp in the middle. But the pattern of the apical part of the elytra, with all the variability, is quite stable - take a walk outside the ZINA! Here is an example http://www.dermestidae.com/Anthrenuspicturatushintoni.html - almost one - on-one, if you ignore the love of Western European amateur entomologists to describe and recognize banal aberrations for subspecies, or even species (well, they don't have enough material, and the desire to "discover-describe" something is through the roof). But there are enough of our own.

Yes, I think: Andreas will compare it himself. I judged from my own region (I have this norichnikovo pond-pond, pohlesche museum enemy will be). And all in the apartment with flowers rushing (infection) smile.gif
