Such a strange creature was found on May 20 on a forest road in a gully near a stream. Somewhere 10-15 mm in length. The larva of a bug?

More like a baby pupa. Like a beetle pupa. The head and legs resemble a leaf beetle...

Pupa is unlikely, there are no rudiments of wings...

Maybe a weevil larva ?

Maybe a weevil larva ?

I have just read (Mamaev 1972) that the larvae of Curculionidae have no legs at all.
Maybe a leaf beetle larva? With metal. Timarcha, for example, has a different color scheme.

Not... it's not a pupa exactly. It was crawling. Just in the photo, it got scared and turned its legs under. The color and softness of the covers resembles a T-shirt.

Here is a photo of the larva of one of the Timarcha
http://en.wikipedia.org/wiki/Image:Timarchalugenslarva.jpg
Please see if it has 6 eyes on each side of the head, and 7 (not 8) pairs of spiracles on the abdominal segments.
Although it's probably not legible in the photo, and you don't have any larvae left, as I understand it.
Is there a bedstraw growing in that place?

That's right - you can't make out the photo, there are no larvae left. But I think that your definition is correct, this is Timarcha, or rather Timarcha tenebricosa - in the area where the pictures were taken, this species is common.

I spread a new beetle-a large staphylin, April 25.

Hedgehog!
MD.15.05.05-at least up
to the MD family.28.06.06 and MD.26.06.04 sharpeners?

Dear Ripper, where do such "grinders"come from? This is some kind of achtung!

10.12.2007 9:58, omar

OK, this is definitely Timarcha tenebricosa.

Isn't maika tsikatrikosys? does not cycatricosus have a coarser punctuation of the pronotum, a thicker bosom, and generally a coarser punctuation everywhere?

Fornax13: I recruited grinders under the bark, mainly, i.e. I took the first one like under the bark, I don't remember exactly, i.e. I found such people both on the bark of a dry stump and under the bark smile.gif
MD. 26. 06. 04 was found under the bark of a fallen trunk, which had apparently been lying there long enough, was all wet.

MD. 28. 06. 06 hardly a grinder like Melandrid or anything else, found on logs, crawling. There were hornbeam logs. If I remember correctly smile.gif

That is, if I understand correctly, this is all from the territory of Moldova?
Something seems to me that this melandrida z.legs 5-segmented. It's very similar to Euknemis.
The one with the combed sawyere is most likely Otho sphondyloides (Germar, 1818), but the sawyere is too much...

is it possible for a male to remove the mustache from the pronotum?

11.12.2007 17:13, RippeR

the segments on the hind legs are very cute smile.gif
By the way, dorkashi winter in what condition? And then in the spring I found new Dorcas under the stones, but not in the winter.. maggots, then?

Take a look

12.12.2007 16:15, guest: Elizar

In Kyrgyzstan (on Issyk-Kul), at the end of August, I found beetles in pupal cradles under rocks. Probably in mountain species - beetles.

12.12.2007 19:56, KDG

I punched through Danilevsky myself. I guessed right.

Thank you so much for your help. Please look at another one. Size 20 mm,

I didn't wait for KDG's response, so I'll blatantly shake it up! shuffle.gif
This is Eodorcadion (s. str.) carinatum ssp. blessigi Ganglbauer, 1884.

Well, now you can sukazat...
I generally agree with the diagnosis smile.gif

good day
Can anyone help. Beetles in the mass (most likely black-bodied), not large, in the passages of bark beetles. Krasnoyarsk Region, under the bark of a pine tree.

Blackbirds of the genus Corticeus. On the second bug, I agree with Budden.

If the beetle is larger than 3.5 mm, it is Corticeus fraxini Kug., if it is smaller, it is most likely C. pini Pz.
This, of course, is estimated for the European part. Although I think that these species are also found in Siberia.
