Please help me identify the weevil. The size is about 1 mm.

It doesn't jump? If it jumps, it may be Rhynchaenus sp. or a close relative.

08.06.2006 10:46, Dmitry Vlasov

No, the "weevil" is clearly not Rhynchaenus, rather it looks like a small fruitworm Curculio sp.? But they have dimensions of about 2-3 mm. Trubkovert - rather B. betulae, a fairly reliable sign-the color of the underside. It is green in B. betulae and dark blue in B. populi, at least in populations from central Russia.

Thank you.
As for the upper weevil: I met the same one today, so he jumps and even very well...
I really liked how the above-presented trubkovert falls when there is a danger - it lifts its legs up in an interesting way, almost straightened-it turns out a very funny "long-nosed raskoryachka":

And this, too, if you can help determine. I believe that the LEAF BEETLE, perhaps even the genus CRYPTOCEPHALUS.
Thank you.

the animal strongly resembles an isopod-woodlouse, although the end of the body is narrowed...
how many legs does it have?

11.06.2006 9:50, Bad Den

to sealor
This is the larva of a dead-eating beetle, most likely from the Silpha or Xilodrepa river.

That's right, a dead-eater larva. I thought about it, but I didn't remember it.

11.06.2006 13:24, sealor

That's right, she is! They are generally usually found dark, narrower. For some reason, I thought it was something out of cockroaches. In general, it turns out that many dead-eater larvae feed on caterpillars. This one is probably also looking for something to profit from, it's not for nothing that she climbed the inflorescence. And there's a flower spider...

11.06.2006 15:23, DHL

Help identify the ground beetle. Several individuals were caught in July 2005 in the town of Ucka, Croatia. The height is ~500-800m, I didn't search for other heights. Caught in trap holes in remote forests.
Body Length (from mandibles) ~16-17mm
once
two
It is better to duplicate the answer to macroglossum@list.ru since I rarely visit the forum.

11.06.2006 17:05, Bad Den

Similar to some Pterostichus (perhaps a subgenus of Petrophilus ?) sp.
But under the big question, I am confused by the shape of the pronotum and the sculpture of the elytra.

11.06.2006 18:08, DHL

100% NON-pterostichus! The front back is much more rounded, and so is the snout. Externally, the similarity is more noticeable with Carabus rather than with Pterostichus...

11.06.2006 22:50, Bad Den

2 DHL
The second photo shows that it is not a Carabus - there is a clipping on the front shins that is missing from the Carabus

11.06.2006 23:56, DHL

Well, it is clear that not Carabus, I say that the probability of Pterostichus is even less)

12.06.2006 9:32, Bad Den

Since the ground beetle is right in front of you, I can advise you to download the necessary part (tables on ground beetles)from the ZIN website "Determinant of insects of the European part of the USSR." and look at it, at least for Rod. If it works, tell me, what kind of family?

12.06.2006 19:52, DHL

No, couldn't determine.. .Maybe even endemic to Croatia? And then there is enough of this stuff on this School, the same Dorcadion arenarium-it seems to be endemic...

12.06.2006 20:42, Bad Den

Where did the antithesis theses even reach?

12.06.2006 23:34, DHL

I went through all the tables, but I still didn't find a complete match.
There is a partial match with the genus Brachynus, but this is not an option, this is understandable)
The antennae are pubescent from the 4th segment, the length of the segments is approximately the same, the first is shorter than the others. Both pairs of tentacles are taporoid, oblique. On the penultimate segment of the labial numerous bristles. There are no pores and setae on the mandibles, the mandibles themselves are of moderate length, resemble the mandibles of Carabus, and are symmetrical. Platypus and v. guba are b. m. symmetrical. Forehead with numerous longitudinal depressions. The chin is simple, without any protrusions and pores. The front basins are closed. Pronotum without keel, breaks off. The front tibia is somewhat extended, but not so much as in scarites. With a fairly deep neckline. The spurs are quite long. On the remaining legs - of moderate length. The paws are not pubescent, the claws are smooth, without notches. The first segment of the hind and middle legs is approximately equal to the second and third combined, or slightly shorter. There are corymbose pores in the posterior corners of the pronotum...

13.06.2006 10:23, Bad Den

How many bristle-bearing pores are there above the eyes?

13.06.2006 21:00, DHL

Above the eyes are two.

13.06.2006 21:35, Bad Den

According to the "Determinant of coleoptera of the Middle Volga region", it turns out something like Amara or Curtonotus.

13.06.2006 23:41, DHL

Well, amara disappears immediately. And curtonotus, too... Absolutely not. Maybe the description is somewhat similar, but the appearance has absolutely nothing in common.

14.06.2006 9:34, Bad Den

Then send a photo to the ZIN:)

14.06.2006 18:31, DHL

I sent it.. Sent)

15.06.2006 9:50, Bad Den

Well, then I can advise you to send the bug itself with a request to identify it...

Help me determine it.

Bad Den, here are the ground beetles, unfortunately yesterday I found only two different ones. The first one, which is larger, flies en masse, in dozens, and smaller ones are less common. There may be others today.

If there is an opportunity to take a picture, then I would like to see a close-up of the antennae, hind legs and claws?

Thank you. Then here are a couple more pictures (also, essno, from the Karelian Isthmus).
