Identification of beetles (Coleoptera)

By the way, on the above resource, these are still two different types.

No, thank you for asking Danilevsky about the differences between these species. In octomaculata, the elytra cover consists of scales, and in subobliterata-of short hairs.
It seems to me that the octomaculata is often very shabby because of the flaked scales. I have exactly such both instances.

Good day to All!
I found this bug at home. Southern Urals, mountain and forest zone, photo April 7, 2017 I found out that this is a red ploskotel. I wanted to clarify to the species, because one is in the IUCN CC, the other is not. And tell me about nutrition. While I keep it at home, there are still snowdrifts on the street, then I will release it of course.

Please tell me - how do weevils of this genus Ceutorhynchus (if I'm not mistaken) differ at all?
I just took a picture on the glass in the room.

Well, here in a nutshell and can not say-how... That's something like this: http://coleop123.narod.ru/key/opredslon/teza_ceuto_1.html

if this is not an optical effect and it really shines so much, then most likely Ceutorhynchus obstrictus, but you need to honestly check the keys

Then I still want to submit these ones for identification. It is clear that this is a different genus, and maybe even 2 species...

I would like advice from knowledgeable beetles. We have some confusion with cows in the region. This specimen has always been considered a black form of Adalia bipunctata. Ukrainian identified it as Harmonia axyridis, although the specimen is one and a half times smaller and does not have a characteristic crease on the suture of the elytra at the apex. However, in the entire history, I have never come across a normal two-dot, only these are black, or just red, with no spots at all. Accordingly, the question is: two-point, or can there be options? In general, now someone is engaged in cows, or the group is completely orphaned?

It is clear that this is a different genus...

Even the family is different - Apionidae: https://www.zin.ru/animalia/coleoptera/rus/atl_cur.htm

The black form of a two-dot, like, does not have white spots on the pronotum and the dots are usually more than two - 4 or 6. So, most likely this is harmony. Red ones without spots are also most likely black.

Aphodius fimetarius or Aphodius foetens ?

you need to turn it over and the question will disappear by itself

Here are the cows:


The top one is a two-dot from Slovakia, the bottom one is actually Harmonia axyridis, and between them there are two rows of what I can't understand at all. In general, are red and black variations of the same species or two different ones? Blacks may have four spots, which can be seen in the photo, but more often the upper spots are reduced and barely visible, or not visible at all. For a two-dot, they are too small and the body shape is not similar, but there is no doubt that this is not Harmonia, because this species has a very good sign, by which it is easy to distinguish it even in the most amazing color variations - it is located on the top of the elytra near the suture itself:

Where are your cows from?
Here there is a suspicion that there are harmonies without folds in Irkutsk. http://molbiol.ru/forums/index.php?showtop...dpost&p=1376433




And in this article http://www.bio.bsu.by/proceedings/articles...0-1-327-335.pdf
it is indicated that in Belarus " Among 56
harmony specimens examined by us, 7 (12.45%) had no elithral crest. "

Here's about the genetics of two-dots http://ecolgenet.ru/ru/system/files/EG_2014_3_52.pdf

I found another article about Harmony http://studydoc.ru/doc/980045/fenotipiches...rmonia-axyridis
It says "The second zone of inter-population stability is located in Western Siberia, where the proportion of individuals bearing a crest does not exceed 20-30% (Blechman, 2008)."

Right here http://www.booksite.ru/fulltext/radch/radch.pdf
an image with the basic shapes of two dots. It is stated that " All
European populations of this species contain beetles with red
elytra and two black spots on them, and so-called
melanistes-beetles with black elytra and four or six
red spots (see Figure 3). Asian populations of A. bipunctata are
even more polymorphic, with beetles with elytra of different sizes.-
personal shades of pink and with a lot of black spots on a red
(or pink) background."


It seems to me that your ladybugs are Harmonies

Amur region.
What is the basis for this conclusion? I don't see a single sign that would indicate this species.

1. The absence of a crease is not an indicator.
2. Black dots do not have (seemingly) white spots on the pronotum
3. There are a lot of Harmonies in your area, and a lot of just such coloring
4. Who else could it be?

Oiceoptoma thoracicum is familiar to me. But what is the name of the second friend could not be found.

Peltis grossa

So I started with this question.

If you do, please report here. It is interesting to know who it is.

What about their hip lines and shin spurs, by the way? I mean, what kind of keys do they fall into? As for Harmonia, there may still be H. yedoensis in the Far East-it is marked for Korea, so everything can be. And it doesn't seem to have this "crease".

We are slowly opening the season.

1. Can we determine Paederus from the photo? =)






2. small, about the size of previous staphylinids

Paederus riparius

It turns out that the pronotum and elytra are of different proportions

Can we say something about aphodia ?

2.


3. Aphodius consputus ?

The topmost photo is probably a male A. prodromus (the bottom image is not clear), below it is some kind of female, but everything is not easy about A. conputus. In general, the subgenus is not easy.

  
2. small, about the size of previous staphylinids

Europhilus sp.

Does anyone know how the Ampedus apicalis nutcracker differs from Ampedus praestus? Can they come across together?

Hello. A friend took a picture of us in the area of the floodplain (forest and copses) of the sandy Kuma River on August 4.

I found this on the Internet:

Staphylin odoriferous, or fast-footed smelly (Latin: Ocypus olens)
List of similar types:
A number of large species of the genus Ocypus found in Europe, such as Ocypus nitens (Schrank, 1781), Ocypus olens (Muller, 1764), and Ocypus curtipennis Motschulsky, 1849, have a solid black matte color and are reliably distinguishable only by their genitals.

Can I say something more specific?
