Is this such a variation in Pachyta quadrimaculata (Linnaeus, 1758), or is it a different species ?
Thanks

Here I have another question about this species, which I first accidentally attributed to Poecilus cupreus.
I ask for help in determining, at least up to the gender.
Thanks

Dear experts,
I ask for help in identifying these beetles from photos in difficult cases, at least up to the genus.
Thanks

36) Judolia sexmaculata Linnaeus, 1758
42) Necydalis (s.str.) major Linnaeus, 1758
Both beetles are quite good, for the M. O., congratulations.

She is this, she is (there is no one else like us). This form comes across sometimes.

35. - Oxyporus maxillosus Fabricius, 1792
37. - Leistus terminatus (Panzer, 1793)
38. - Melandrya ?dubia (Schaller, 1783)
44. - Chilocorus ?bipustulatus (L., 1758)
45. - Gonioctena ?viminalis (Linnaeus, 1758)

and the fact that "Poecilus cupreus" IMHO resembles more Chlaenius (for example, Chlaenius nigricornis)

Alexey, so maksilozus is still (his belly is abnormal)? Although in general, there seems to be nothing else to offer.

28 Athous vittatus

By the way, yes. I'd forgotten all about Vittatus. But it is better to take a photo of the mounted beetles, otherwise it will be useless.


Is it the same view?

Thanks !!! Live and learn forever. And in all the determinants I have for some reason Melanotus rufipes .

#8 The pronotum would be larger and more honorable (now I also doubt the vittatus).
C #28 and so everything is clear-A. vittatus.

1) Dalopius marginatus( see here http://www.elateridae.com/zobrbruk.php?id=3328)
2) Athous vittatus (see here http://www.elateridae.com/zobrbruk.php?id=3111)
These are 2 different types they even have different Russian names The Nutcracker is bordered and the second one in my opinion is a multi-colored Nutcracker (something like this).

Here is a photo of Dalopius marginatus from my collection(I apologize for the quality I caught it 4 years ago and did not know even then how to make beetles, stupidly glued to cardboard)

It turns out that No. 8 is Athous vittatus, which is well disguised as Dalopius marginatus. But you can't fool us umnik.gifAt my No. 8 PRSP is not bordered and the outer edge of the NDKR is painted dark brown. To understand better, it is necessary, of course, to soak the beetles and mount them.

Thank you very much

beer.gif beer.gif beer.gif

No. 8 caught in early spring
No. 28 caught in mid August

I caught it 4 years ago and didn't know how to make beetles back then, I just stuck it on cardboard


So it's not a problem! In hot water for two or three hours, they will peel off again and you can straighten them out. I once undertook to remake all the beetles. I decided to re-glue from large dies to small ones, so that the needle would be on the side. Everything worked out, I didn't spoil a single beetle.

Dear experts, unfortunately, I was unable to insert images directly into our forum. Swears on the size, although I have a smaller file size than the forum requires. I filled everything in on Radical again. When there is a lot of traffic on the Radical, it starts to hang and the photo doesn't open, but at this point, there is usually a "get links" link. If you open this link, you can copy the link to the photo without waiting for it to open. This may be an extra hassle, but it's better than waiting for hours. smile.gif

I ask for help in determining, in difficult cases, up to the genus.
Thank you.

With these two, I have a stupor. I know that these are easy-to-define views. Due to the temporary absence of a determinant, I used pictures on the Internet, but there is no order. With a gray mustache, they call both this and that, with a black mustache, the same story. So, I ask for help, at the same time I will learn to understand them. Thanks

Make the image 800x600 or smaller and everything will be fine.

47a-b-looks like something interesting from the Scirtidae, as an option-Elodes.

Dear experts, please tell me, is the beetle on the right in the photo an under-colored Harpalus rufipes, or is it some other species? MO

Isn't No. 3 (10mm) too large for Phyllobius calcaratus?
What should I pay attention to?
