Anthribus sp.

Thanks! At first, the short mustache was disconcerting... and it turns out sexual dimorphism...
Who would have suggested it? Clearly not Platystomus albinus. On the Zinovsky site, I didn't find a photo of such a handsome man.

Give the upper hand!

Yes, top!: (the file name is wrong, of course)

Platyrhinus resinosus

jump.gif Do you know how far north it goes?

24.09.2007 11:48, omar

There is one in the Moscow Region, but I won't say any further.

As for sosnovaya, you also need a top for confidence.

There is no top. But, I think, not pine. Too red, and shot in Mugojary. Southern steppe, there is no smell of pine. Or is it not important?

24.09.2007 12:21, omar

Important! It is almost impossible to get far from the pine tree. I also wanted to be surprised that in the steppe. And what conifers are there?

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...

The fact is that both morphs (both the typical black morph and the metatarsalis morph) are found together. They can often be seen on the same plant, copulating, etc. And two subspecies in one place-however, this is impossible (if there are no ecological niches or seasonal division). And in the lower picture, these are quadripunctates - don't be confused by their orange color. With a solid sling in the center - M. quadripunctata ab. adamsi.

I also thought it was May Day. But this drawing was given in a report about leaf beetles lol.gif

I believe these May beetles in this article are for filling in space and have nothing to do with the text. umnik.gif

today, out of the traps. Cichruses like semigranosus.. help me understand smile.gif

#3 and #4 are most likely Amara sp. You need to look at the determinant. umnik.gif
They were both captured in the vicinity of Chisinau? confused.gif

not the neighborhood of Chisinau, but Capriana.

Horse from the Orenburg region - Cylinders germanica. Although this species varies in color, it seems that here it is more about how the light fell on the beetle... They are common here, but other Cylinders have not been caught at all yet. For that, this year I caught Myriochila melancholica for the first time.

And three more elephants. The first one is a crumb (3 mm) from the Middle Urals. The other two are from the steppes of the Southern Urals.

1. I would say - Polydrusus of some kind. And on what?

2. Larinus vulpes Ol. like. What size is it? Weed, as far as I understand, Echinops of some kind.

3. In my opinion, Hylobius transversovittatus Goeze-also lives in the steppes, on our Lythrum near the water. I'd like to see it from above. And what does this animal eat in the photo?

PG18,
In general, coccinelids are quite easily detected if you fill your hand and eye.

Yeah, Scymninae in particular...wink.gif

For several hundred kilometers. Is that the Kazakh juniper...

The first elephant was caught in the car.
The second one really looks like E. sphaerocephalus. Or a different kind?:

About a centimeter.
I can't specify anything about the third one. Not my frame.

25.09.2007 7:30, PG18

And in the lower picture, these are quadripunctates - don't be confused by their orange color. With a solid band in the center - M. quadripunctata ab. adamsi.

Wow, I'm still confused by this color variability. Without special training, it's hard to believe that two right-wing beetles are the same species... picture: Meloidae_Hycleus_atrata_0045________.jpg

Today I will try to look at the collection...

  jump.gif Do you know how far north it goes?

It is found throughout Fennoscandia (including Karelia and the Baltic Republics (I found this in the list of Fennoscandia beetles).

So I made a mistake weep.gifWhat does it mean - I don't know the Eastern ones at all. After all, I thought that there might be some eastern Hylobius. By the way, where is Fornax "at us"?

Oh, I got Milabris with my milabris, but I really want to figure it out... Well I can't have these beetles
picture: Meloidae_Melabris_sp_0043________.jpg
quadripoint to sign...
First, they are one and a half times smaller (in length, see my two photos from yesterday)
Secondly, orange, not red
, and the drawing...
We have in our collection (Institute of Plant and Animal Ecology, Ural Branch of the Russian Academy of Sciences) all these species(?) they stand in small groups, but not clearly defined frown.gif.
Do their genitals work (as keys for identification)?

It appears to be a male O. (s.str.) taurus (Schreb.) f minor.
Pubescence, like, elytra do not see.

In which determinant to view, for the exact definition.

I think exactly L. (s.str.) vulpes Ol., very similar. Ещё inaequalicollis Cap. it exists in nature, but it is unlikely that this is it.

The first is something like Polydrusus cervinus L. But I may be wrong - I'm not very good at short drones.

I keep confusing which one is sphaerocephalus and which one is ritro. But beetles, in my opinion, do not care about this question-they both eat and do not complain about thorns. There is also E. pungens - I can hardly imagine it (Larinus inaequalicollis is indicated on it).

I work with some Polydrusus myself, I've seen enough pictures, it seems really similar to cervinus, but judging by the books 4-5. 5 mm and the author wrote 3mm? Maybe there was no exact measurement, by eye?

In principle, you can consider Doristenes as a subgenus. Some write as a genus, others as a subgenus... Do you have a lot of them?

I see, thank you.
I have these 3 copies of them (2 walkeri + granulosus) + 2 in a souvenir box without labels (I'll post them in the evening)
