Caucasian Bambi up to a maximum of subgenus pull... frown.gif
1. Similar to Neph just. If the grooves on the CD are erased, almost imperceptible, and there are 2 spots on each CD, then one of them.
2. Peryphanes, in my opinion. Elytra are unicolored if.
3. Elaphrus is too large for aureus. And it's brilliant, too. This is either uliginosus or cupreus. If the legs are unicolored metallic and the head is not wider than the pronotum, then uliginosus. In cupreus, the lower legs are lighter and the head is wider. The color of the top is more similar to uliginosus, but it is better to look at the signs.
Caucasian pterostichines are ppcs by definition... smile.gif

Another ground beetle near Moscow. I remember that a similar one was defined as Pterostichus oblongopunctatus. Looks like it? About 15 mm in size.

1-Similar to Agonum. Probably gracilipes. I overreacted with Europhilus.
2 - Cute something from podtr. Stenolophina. Is it a big animal?
3-Not, lied, not Harpalus. Whiskers with the 4th member are pubescent. Maybe Curtonotus is so...
4-Quedius some. m. b. from sensu stricto.
5 - Dacne bipustulata (Thunberg). It is from the Erotylidae.

No. 3 is about 5-7 mm..it's hard to say more precisely, there's a bug at work.
and with No. 5 I completely agree with you!! here I found that in Jacobson the families Cryptophagidae and Erotyidae are united together, tomorrow I will work on why I went to the wrong family in green.

for dzadat.... here, however, is not an important trick, a copy of which I asked, a rather shiny wheelbarrow, 4 very grated teeth (such were when caught), a few hairs along the seam on the wheelbarrow, there are small but distinct points on the elytra aisles (which is not typical of a typographer), there is also no bump on the forehead. Well, the color of the beetle is almost black

In the middle zone, a common species, years April-May, adults appear in August-September, overwinter. In the spring, it flies well into the light. It is somewhat more difficult to collect manually, because during the day they hide under the bark, on trunks, etc. places.

Hello gentlemen! - I am completely discouraged by my inability to identify (i.e. distinguish from similar species) this ladybug from the tribe CHILOCORINI. Caught 20.09.08 Dagomys (Sochi) on the abandoned territory of a furniture factory.
Here is a list of 5 similar types:

Chilocorus renipustulatus

Chilocorus cacti

Chilocorus kuwanae

Chilocorus orbus

Chilocorus stigma

02.10.2008 13:42, Alexandr Rusinov

For me duck Chilocorus renipustulatus

02.10.2008 13:58, Buzman

I think it's him, too. There aren't many options. In addition, it is very unlikely that you could catch Chilocorus cacti or, for example, kuwanae in the area of Dagomys wink.gifIf I am not mistaken, all the species listed by you, except renipustulatus, are common in the New World

Chilocorus cuwanae is listed for the fauna of Russia on the ZIN website, but unfortunately it is not indicated where it is distributed. http://www.zin.ru/Animalia/Coleoptera/rus/cocc_ru.htm

02.10.2008 15:16, Buzman

Chilocorus cuwanae is distributed in the Far East, China and Korea, as well as introduced to the United States. I think your chilocorus is Chilocorus renipustulatus

1.picture: P3210054_.jpg

In my opinion, still Sphaeriestes. If there is no metallic ebb. Colposis and Rabocerus are clearly bronze and have a slightly different muzzle.
I think it is Sphaeriestes stockmanni (Biström, 1977) (= ater (Paykull, 1798, non Degeer, 1774)). Really, catch some more smile.gifSalpingids-the beetles are good smile.gif
And how did you put it together, if it's not a secret? wink.gif

for zad'at.... here's the really not important trick I asked about, a pretty shiny wheelbarrow, 4 very grated prongs

I. subelongatus.
cembre is a western species and morphologically hardly distinguishable from subelongatus, so the fact that in Siberia it is I. subelongatus, the same from the west - cembre! this is how they are defined.

I am also inclined to this definition!!...and I have read a lot about the similarity of these species, I am confused by the totality of signs and the main thing is that the wheelbarrow is almost hairless...and for some reason, just such specimens with such worn teeth and such a color...
well thank you for confirming smile.gif

I'm not good at these beetles at all, and by the way I grab everything that moves, I sometimes come across something interesting...
In particular, this was the case when analyzing pheromone traps for bark beetles. One of the non-target views. This year in larch forest, Khakasia

are these tree-eaters or something?? confused.gif

03.10.2008 16:24, akulich-sibiria

although it is similar to Trixagus on Monday I will look at it under magnification

03.10.2008 16:53, Fornax13

To akulich-sibiria:
These are the Throscidae, of course. But not necessarily Trixagus. Look him in the eye: if they are whole (not separated), then Aulonothroscus. It reminds me of A. laticollis (Rybinski, 1897).
As for larches , it is quite likely: according to lit. data, Sphaeriestes are more often associated with conifers.
