about the 1st still need to work..
2-true
3-too. however, I would still add a subspecies of irregularis Harold. But I don't insist.
But in general, you do a good job yourself. It's time for me to join the audience

It's a little early for the audience

And the first one is approximately from what tribe?

20.09.2007 12:20, RippeR

akulich-sibiria:
according to the idea, you only have arietoides. Arietis is a European species.
Racehorse, most likely Cicindela nitida optata

from the same company. His name is Titoceres jaspideus (Serville, 1835). Kind comrades suggested it. in general, tropical Lamiinae for definition are atas complete. and africa is not the worst yet.

Here laid out here ptrerostikhusov (Bothriopterus) on a mattress) from the Moscow region. And I noticed the following.

According to the determinant, there are two types of occurrences.

A bunch of typical angustatus. A bunch of typical oblongopunctatuses.

Further. Among oblongopunctatuses, specimens with a wider prsp are distinguished - without bronze in the gloss - of a larger size - with a maximum of points. They are caught in the same place as oblongs.

And everywhere it is indicated that oblong SHOULD have a bronze sheen.

http://nature.doublea.ru/pix/pterostich_op3.jpg "that's the one

http://nature.doublea.ru/pix/pterostich_op2.jpg "typical oblongo..

is something wrong here, or do I not know something?)

21.09.2007 23:41, Fornax13

Yes, I would say that oblongopunctatus doesn't care. We have some of them, too. Some kind of gloss seems to be available, besides the color of the legs is typical. And the species is very variable (in the Caucasus, blackfeet are generally ssp. melanoscelis, but the species is the same). And what is the gender of this creature?

Aren't they all females?

22.09.2007 0:14, Sparrow

all females

but! there are also standard females... I find it interesting that all 4 of these attributes are concatenated. no intermediate stage)

22.09.2007 7:33, amara

R. oblongopunctatus seems to have a similar species, R. adstinctus Esch. which I don't know anything about ( it doesn't exist in Isaev). It is found in our country at least in Karelia and Siberia. Try searching the Web.
The heterogeneity of P. oblongopunctatus confused me myself.

help me identify the horse, otherwise it is brown on one wing and emerald on the other..

99.9% is Cicindela hybrida L.

23.09.2007 0:43, Fornax13

That's what I thought. Female ground beetles tend to be larger, broader, and more opaque on average. And the number of points in this species varies from 3 to 12, in addition, it largely depends on the conditions of larval development. Although it is really strange that there were no transition forms. But perhaps in large samples they could be. What is P. adstrictus Eschsch? I don't really know either, but as far as I can tell, it's a terrible taiga creature. Maybe it replaces our oblonga to the north - I don't know. Just 3 close species with similar ecological needs in the same conditions is quite a tin.

Right here http://www.habitas.org.uk/groundbeetles/sp...s.asp?item=7278 some information (on ecology and distribution). in Ireland) and photo of Pterostichus adstrictus Eschscholtz, 1823

And edes http://www.habitas.org.uk/groundbeetles/sp...s.asp?item=7297 reflections on what (dampness

may determine the number of pits in Pterostichus oblongopunctatus (Fabricius, 1787).

Help out with two South Ural horses.
The first one is from the south of the Chelyabinsk region (a typical steppe). It doesn't seem to be a field one... Or is it him?
The second - third - from the very south-east of the Orenburg region (almost semi-desert).

The first one seems to be field
and the second and third are germanica, I think. Or at least the Cylindera sp.

are there any Germanics in Orenburg region at all? If it wasn't so shiny, I'd say gracilis... but those are frosted..

If you look at the pronotum, the first cichrus seems to me to be semigranosus (the pronotum is slightly heart-shaped), and the second-carboides, the pronotum is round

No, it's not an adstrictus after all) since all of mine are collected in the forest in ditches. We have a field adstrictus.... and in my opinion, there is no such thing in M. O.. although... In general, while they are marked as Bothriopterus sp. then I'll make more samples and see what happens....

PG18, I'll try to help with coccinelides.

5 и 9 - Anatis ocellata L.
3 - Neomysia oblongoguttata L.
8 - Halyzia sedecimguttata L. But I'm not so sure.
In general, coccinelids are quite easily detected if you fill your hand and eye.

Thank you for getting started. I managed some of the others myself, but 4 types (pj, see prev. p.) are still too much for me.
I'll be waiting for my colleagues with a full eye

PG18, 8 - Halyzia sedecimguttata L. But I'm not so sure.

8-rather calvia quatuordecimguttata

Is that how they mate?

And is it correct to call the prevailing morph an aberration?

Well, this is the predominant one, and the typical one (described from the Zaisan district) is very common in the south. It is characterized by black elytra with two bands at the apex. And on these photos-metatarsalis yes plus even quadripunctata.

Thank you for the explanation. But still, if we have a predominant dark morph, then apparently we can talk about a subspecies. The very term aberration I used to perceive as a rare atypical (anywhere) deviation. But that's okay... Who are the orange ones in the bottom picture? Neither quadripunctata, it is significantly redder...
