Yes, I also suffered with the alleged heydenianus, but I never decided. In general, and with the subgenus, too, not everything is completely clear. According to the Zinovian data, heydenianus must occur in that area. In short, if you find any more complete information, please knock me smile.gif

Po-vidimomu, na snimke - Pterostichus (Myosodus) rudestriatus

Thanks for the informationsmile.gif, I'll try to find pictures of this species on the Internet to make sure.

Not a big cow 4-5 mm.
Astrakhan region. Found on alfalfa.

This is Exochomus flavipes (Thunberg, 1781)

Yes, but where would you get at least some of the literature listed by you? Maybe someone knows where in the network you can find something from the above? And with the picture I really have a bummer-it came out: nothing, no search engine helped.

Thank you for your clarification! As I understand it, if the ground beetle is deltomerine, then this implies that it has hairs on top of its legs (based on the" Determinant of insects of the European part of the USSR Vol. 2", family Carabidae, description of the genus Deltomerus)? My ground beetle has no hairs on top of the legs, there are only a few rough bristles sticking out of the joints of the legs. It turns out that this is really Myosodus. Only, I'm afraid that even in the most extensive of the geographically accessible libraries (Kursk) I don't think I'll find anything serious about Myosodussmile.gif, but it's worth a try, in case I'm wrong.

19.08.2006 1:12, Bad Den

Is this ground beetle suitable for Pterostichus?

19.08.2006 10:55, Necrocephalus

Well, it seems smile.gifthat I'm just such an expert on carbides that I can't say for sure. And as for not belonging to Deltomerus-that's for sure, because there are no hairs on top of the foot.

21.08.2006 20:38, Necrocephalus

Please look at the photo (although it came out rather badly), maybe you will find out who is depicted on it? This beetle I caught today on a pine stump in a pine forest - in appearance-poured Archopalus rusticus from the ZIN website. One thing is confusing - why is there no such Archopalus in the "Determinant of insects of the European part of the USSR" vol. 2? I don't think this bug is not there, maybe it is somehow named differently there? And can Archaeopalus rusticus occur in the Kursk region? When I tried to identify the beetle from this identifier, it turned out that it should be one of the Tetropium species, although the beetle did not quite fit the description of this genus... Please help me figure it out, otherwise I'm confused about something smile.gif

In the "Guide to insects of the European part of the USSR", Vol. 2, it is listed as Criocephalus rusticus L.
It is distributed throughout the European part of the Russian Federation.

To Necrocephalus
Most likely, indeed, A. (C.) rusticus. I met him in the pine forests, in clearings from the south of the Pskov region to the south of Belarus, so there is a must near Kursk. See also Asemum striatum - they are a bit similar.

Confirm! - Your barbel Arhopalus = Criocephalus rusticus (Of course there is a chance that "tristis").

Thank you for your help! I studied my beetle in detail - more precisely, two, one was caught, as I wrote, on a stump, and the other was found dead near a log-both belong to the genus Archopalus (Criocephalus), because the antennae reach the middle of the ndkr., and to the species rusticus, because there is a whole complex of prisankov characteristic of this species. Thank you all again for the hints, the question can be considered exhausted smile.gif

To Necrocephalus
Going Back To Your Barbel,
2Necrocephalus
Confirm! - Your barbel Arhopalus = Criocephalus rusticus (Of course there is a chance that "tristis").

It is possible that tristis, which is now called A. ferus (according to Filimonov, "Barbel beetles of the Leningrad region"), by the way, in the same Danilevsky tistis is reduced to synonyms rusticus. Here is what he writes:
"After Silfverberg (1979): A. rusticus = A. tristis. Sama (1991) also excepted identity of the type of Callidium tristis F., 1787 and rusticus L., 1758, but Lipp (1937) declared identity of tristis and ferus Mulsant, 1839. Evidently, different type specimens exist. Is it possible to except Lipp's opinion as first?"
In short, I don't know who has it right, the main thing is that in ferus (tristis) the third segment of the hind leg is dissected to the middle, and in rusticus - almost completely.

The body length of various specimens is 4-5 cm. Whiskers are one and a half times longer than the body. Taken in the Moscow region.

It appears to be a barbel from the genus Monochamus. Most likely Monochamus urussovi (Urusov's Creeper)

That's exactly what it is.

I completely agree with you, in our Krasnoyarsk Territory, dark coniferous grass is quite seriously damaged.

25.08.2006 9:53, Dmitry Vlasov

In the European taiga, too, a common pest. Windbreak firs are all in the exit holes, as after the shelling...

25.08.2006 12:33, Nilson

I join-M. urussovi Fish., male, of course.

28.08.2006 9:21, BO.

Help me determine it. Small ladybirds ~8mm.
Astrakhan region.

Who is it? Pay attention to the fovea on the pronotum. Could it be Phaenops cyanea? Please excuse the poor image quality.

It seems similar, what color is it? and the size?

31.08.2006 17:59, Necrocephalus

To Elizar: the color is very dark blue, almost blue-black, the beetle on top is slightly shiny, with a slight metallic sheen. The bottom of the gold leaf is greenish-blue, and it glitters much more than on top. Elytra are very densely dotted. Size-8 mm
. P.S. Thank you for responding smile.gif

01.09.2006 7:50, Dmitry Vlasov

Well, then Phaenops cyanea, although they are usually either blue or greenish on top. Almost black ones are rare. Or the beetle has darkened after soaking and drying )it also happens...) And the pits are more likely due to some "injuries" of the pupa or larva.

I don't know, like and live the same was... And the pits-yes, if you look closely, a slight asymmetry is noticeable... Thank you, now I will know that this is Phaenops cyanea, otherwise I would doubt it.

And here is this that for zlatka, can who knows? Not ours - from the Balkans.

Zlatka is definitely Chrysobothris, but at the expense of the species... In the Balkans, there may already be anything, maybe even the fauna of the USSR can not be determined. It looks like affinis in general, but it also seems to be geographically variable - beetles can be very different from different places!

Yes, I understand... Here, I intend to meet with Volkovich.

I decided from the branch "Fishing reports" to throw here. Here is a pair of M. galloprovincialis that I caught in Montenegro. Maybe, of course, this particular one is not quite different from "ours", but there were also almost completely light views. What is the subspecies, can you tell me?

Judging by the list of barbels of Europe by M. L. Danilevsky (website "Beetles and coleopterologists"), Montenegro has the same subspecies as ours - M. galloprovincialis pistor. If you really identified them correctly.

And the right instance is exactly galloprovincialis? In the photo, it seems like the shield is completely divided by a bare strip?
