and they also seem to be more and more green, by any chance not miroshnikovi?

Well, no, they're mostly purple. In C. miroshnikovi, the range is east of the Belaya River.

Thank you, but is the subspecies exactly nominative, or are others also possible?

There is a form nubicola Zolotarev, 1913-this is an alpine form at altitudes from 1500 m above sea level. For example, the Lagonaki plateau. In this case, I am still inclined to the nominative subspecies. The photo is not very informative, you can hardly see the prsp sculpture. In general, prometheus ssps clearly differ. from miroshnikovi ssp. the structure of the endophallus. The locale you specified has quite wide borders. West of the Belaya River, I have not seen any finds of ssp. miroshnikovi on labels. If you blow out endophallus, the problem will be solved in one-digit way.

I found this very small gold leaf on a flower (bud?)today. weeping willow in Moscow. There is little hope, but it may still be possible to determine it.

genus Trachys, but the view should be viewed, possibly minuta, the bandages on the elytra are not visible

Carabus (Archiplectes) sp.
Republic of Adygea, Krasnogvardeysky district, Rufabgo river, male, 29. VII. 2007 I. A. Yudakov
length-34 mm

Rufabgo waterfalls - this is the left bank (West) of the Belaya River. So most likely you have an A. prometheus nominative, as noted by Enthalex. You can take a look at the nominative from near Maikop (almost from the same Belaya-Kurdzhips watershed). By the way, in that area, near Khadjokh (Kamennomostsky) I came across a green color form more often.

hello.a couple of questions about cows
1. I can't get out on the view, a genus like Scymnus as a variant of ferrugatus
picture: PA230001_.jpg
picture: PA230002_.jpg
picture: PA230006_.jpg
2. can there be Scymnus abietis, although it was caught in a birch tree, not on conifers

and another question about leaf-eating....although the photos may not be very successful. I am entering the genus Asiorestia (=Crepidodera)...as a variant of ferruginea or sublaevis? maybe someone will help.. mol.gif

And in Scymnus, which is a variant of ferrugatus, the tops of the elytra are at least partially colored?

09.05.2009 23:30, DIMac

Crepidodera rufous species in your region: impressa, transversa, ferruginea, interpunctata and crassicornis. It is most likely Asiorestia ferruginea (Scopoli, 1763).
http://www.biol.uni.wroc.pl/cassidae/Europ...0ferruginea.htm

Scymnus is definitely not ferrugatus. Perhaps this is Scymnus depressus
Scymnus abietis will also be more elongated (it looks rather rounded in the photo)

10.05.2009 0:07, Алексей Сажнев

for some reason, it seems to me that Scymnus abietis is some kind of under-colored beetle

10.05.2009 7:28, akulich-sibiria

And in Scymnus, which is a variant of ferrugatus, the tops of the elytra are at least partially colored?

this is the point, that I did not find any lighter spots and edges on the upper wings..they are evenly colored, dark brown like that..and there are no pronounced spots on the pronotum. The femoral lines seem to be full. It was caught in a greenhouse on plants where there were a lot of aphids in the mass.
how can the variant be Scymnus rubromaculatus??

I agree with you about the leaf beetle. According to Medvedev, this is the closest species to the description, and it is difficult to say anything about Scymnus abietis. The femoral lines are clearly not complete, do not form a complete semicircle. And then there I was mostly guided by color. And what other type can there be in this case?? YES, his body is quite rounded

10.05.2009 10:50, Алексей Сажнев

Scymnus rubromaculatus is quite possible as an option, but is Scymnus depressus a valid name?

10.05.2009 12:26, akulich-sibiria

Scymnus rubromaculatus is quite possible as an option, but is Scymnus depressus a valid name?

the only thing that bothers me is that the femoral lines are not complete for this type...
And a valid view, is it a synonym for**?

10.05.2009 13:00, DIMac

yes, scymnuses have very young imagos all on the same color - from white to light yellow

- Savoyskaya G. I. Koktsinellidy (systematics, application in the fight against agricultural pests) / Alma-Ata: Nauka, 1983. 248 p
.nothing more detailed on our cows was not found (186 species from the USSR). maybe V. N. Kuznetsov also had more modern tables

ladybugs are one of the most diverse in color beetles in all senses. sometimes 20-25% of species are added to this family. apparently because of the huge number of implicitly differentiated forms, and scimnuses are generally darkness))
So we continue to bomb the Aedeagus smile.gif

Valid is that recognized ))) but Scymnus depressus neither in the fauna of Russia, nor where in modern publications, I did not notice something, apparently it is reduced to synonyms, but to whom?

10.05.2009 13:43, DIMac

I'm sorry - not genus Scymnus Kug., but genus Sidis Muls. weep.gif
S. depressus from the fauna of the USSR (according to G. I. Savoyskaya, 1983). The basal lobe is about the same length as the parameres, finely pointed at the apex, parallel on the sides, massive in profile, broad at the base, tapering sharply on the ventral surface from the middle to the apex and deeply incised here.
The femoral lines almost reach the lateral edge of the sternite. Shoulder bumps are barely visible. Elytra are brown
. depressus Sav. - actually Savoy and described, and related to S. elongatus Sav.
probably now the genus is revised. coccinellidae.net silent about Sidis

four out of five are missing. bombed means the newfound "species"))
and nephuses like before that were a subgenus of scymnus. here everything is crushed, combined and crushed again. a pleasure))

Diaperis boleti (Linnaeus, 1758)
Platycerus caraboides (Linnaeus, 1758), although caprea is also possible-see the differences here http://www.zin.ru/animalia/coleoptera/rus/platyce2.htm
Semiadalia notata
seems to be similar to Oedemera virescens, the male
reminds me more of Cicindela (s. str.) soluta-brown form, I don't know if you have takie

2. - Adalia (s. str.) decempunctata (Linnaeus, 1758)
3. - I agree Coccinella nivicola Mulsant, 1850
1. - possibly Adalia bipunctata fasciatopunctata Faldermann, 1835-not sure

10.05.2009 22:17, akulich-sibiria

some difficult to understand types 1 and 2..something little info on them...here on the second one I went to Adalia bipunctata frigida vyrode it is characterized by splitting or vice versa the formation of bandages, well, at least I determined by DV, I think wrongly...and 1 (though for some reason the angle from the back slid to the very bottom) I go to Propylea or Calvia? her eyes are partially hidden under the pronotum

10.05.2009 22:44, Алексей Сажнев

well, then it can't be a variation of Propylea?

11.05.2009 7:34, akulich-sibiria

the ladybug was a little larger and there was something disconcerting about the arrangement of the spots. The bug is at work, and tomorrow I'll try to run it through the keys again.and at the expense of 1 ladybug, is it exactly A. decempunctata??

11.05.2009 8:43, Алексей Сажнев

at the expense of A. decempunctata-I think yes it

Can you tell me if these are two different species or a variation of melolontha hippocastani? confused.gif
09.05.2009
Moscow region, Odintsovo district, Krasnoznamensk.
on light
#2 is slightly less than #1.
I didn't measure it with a ruler, but it is visually smaller, shorter by 3-5mm.
Moreover, two males No. 1 and two males No. 2 were caught, which is why the question arose, and when I caught the first No. 2, I immediately recorded it in hippocastani

[attachmentid()=62796]

11.05.2009 19:33, Алексей Сажнев

if you suspect Melolontha melolontha, then check the antennae - in males of this species, the 3rd segment is in the distal half with a weak tubercle, but this is unlikely in the western crunch - the process of the pygidium is not thickened at the end, but the same width throughout.

in my opinion, the hippocastani subspecies is too far in its distribution from the MO, one in Transbaikalia, the second in Italy, and the species is divided into variations more in color than in the processes of the pygidium, and the size of the species varies from 20.5 to 29 mm-so I think this is Melolontha hippocastani hippocastani
