Identification of beetles (Coleoptera)

This is the cow Myzia oblongoguttata (L., 1758).

If there is an opportunity to take a picture, then I would like to see a close-up of the antennae, hind legs and claws?

I hope this is enough to determine?
What kind of flyer? It looks like an ant lion.

He is.

I hope this is enough to determine?

Now it is clear what it is:
not Lasiopsis, not Rhizotrogus, not Holochelus
How many segments does it have in its antennae (3 in the club and in the stalk, how many more)?
In the photo, unfortunately, it is not very clearly visible

In my opinion, you can count. I can't find a better one.

Great photo!:) What kind of camera did you use?
With a 90% probability of Chioneosoma sp.
And you can also have large claws in profile and jaw palps?

Another beetle from the Leningrad region



The author of the photo called it "May". But IMHO-a typical bronzer. If so, which one?

This is bronze, Potosia cuprea metallica (Hbst.)

Thanks! panasonic z30. Everything I found.

Yeah...
After all, this is probably Lasiopsis sp. or a close family (judging by the claws)...
But then it should have antennae of 9 segments (in the first large photo of the antennae I counted them 10)....

Well, I'll try to look at that biotope in detail. I hope to find there , although this is too much, a steppe dybka.
And this is for fans of coleoptera-yesterday flew to the light, what is it called? In general, yesterday was a good year, flew Amphipyra pyramidea and a few more scoops.

Trichoferus pallidus is a great barbel, in my opinion!! I've never seen such a person before.

Found today on the sidewalk in the zoo, unfortunately, it looks like it was stepped on more than once, but still the appearance is specific, can anyone find out? Size ~3.5 cm.

Either Aromia moschata (Cerambycidae) or Lytta vesicatoria (Meloidae)

Lytta vesicatoria exactly, according to Plavilshchikov, the signs converge, there is this species. Interestingly, I kept it in my fist for a while, it's been 7 hours, there's not even any redness. True, the beetle was crushed like a long time ago, and the hemolymph dried up.

Indeed, on the legs and antennae it looks like a punky fly. Strangely, I also held it in my hands, like many other abscesses - no hints of unpleasant sensations.

For unpleasant sensations, IMHO, you need to crush and rub into the skin, or swallow:)

Bad Den, thank you! Barely found anything on this view. According to the materials of one faunal article, it was caught in the grass steppes. Among the mass of" identical " ground beetles, this is one such. By the way, when there are a lot of them flying, the smell is terrible...

Hello to everyone who is interested in insects! In July, I was a tourist on Dombay (North Caucasus), caught 4 interesting ground beetles-under flat rocks, at an altitude of 3000-3200 meters. Two of them seem to belong to the genus Carabus, but to different species, and two more-it is not clear which genus, but to the same species - they were even caught side by side, under the same stone. That's what I want to ask the respected public about: can someone tell me who they are? In shape, they are most similar to this ground beetle: only the elytra are slightly less wide and more elongated. Next, I will try to describe their color as fully as possible: the top is completely black, the bottom is brownish-black, all the thighs are reddish-red, with black tips, the lower legs, paws, and antennae are also black. The head and pronotum are shiny, the elytra are less shiny, with 8 rows of small, oblong indented dimples of different lengths (like the surface of a CD under magnification). The mandibles are also black, with a simple sharp tip curved inwards. In length, the beetles are both 17 mm long, without taking into account the mandibles, which protrude forward by about 1.5 mm. The beetle itself is quite flat, looks elegant. Today I downloaded " Determinant of insects of the European part of the USSR. I spent the whole day poring over it, but, unfortunately, I have to admit that it is not up to my teeth - I could not identify any ground beetles brought from Dombai. My level (so far) is a more or less tolerable mastery of the technique of determining by the Plavilshchikov determinant, using the pictures in Gornostaev's book
By the way, I want to add that I am very glad that I finally got to a real entomological forum.
One more small question: on the site "Beetles and coleopterologists" I saw a lot of clear and high-quality images of insects, made, as I understood, using a scanner. Is it possible to use a regular, household scanner for this purpose (which is usually used for scanning documents, etc.), or is some special device needed in this case?

Perhaps it is some ground beetle from the subfamily Patrobinae, or, for example, from R. Leistus (your mandibles are not dilated, by chance?).

No, the mandibles are the same shape as most ground beetles, but they don't look dilated. Tomorrow I will try to take a photo using a digital camera, I don't know if I will get a normal photo of such a small object?

17 mm - it should work.
It is better to use the scanner with a CCD-matrix, and in" ordinary household scanners " the CIS-matrix is used (it has a lower depth of field). Although, in truth, the CCD matrix is not always a panacea: my Epson 4180 Photo perfectly scans photos in a frame with a height of 3-4 cm, but it is not able to completely sharply scan a beetle lying on the scanner glass - only the areas directly adjacent to the glass are sharp.

If not for the color and small size, then I would assume that P. heydenianus - I caught them quite high in about the same area, but it doesn't look like it. Your ground beetle is apparently not a carabus.
I replaced it with a household one - only beetles bigger than a rhinoceros turn out well. Now I switched to a digital soap dish - it turns out much better!

Today I downloaded " Determinant of insects of the European part of the USSR. I spent the whole day poring over it, but, unfortunately, I have to admit that it is not up to my teeth - I could not identify any ground beetles brought from Dombai.

Caucasian ground beetles can be defined up to a maximum of a genus by this determinant, but it simply does not include species from this region
Tell me, does this ground beetle have a tenderloin on its front legs?

Thank you for your tips! Today in the second half of the day they should bring a digital camera with the possibility of macro photography, I will try to take a more or less decent picture of my ground beetle.
2 Bad Den: yes, you are right, there is a tenderloin on the front shins, with a spur sticking out of it. Tell me, what determinant should be used to identify ground beetles in the Caucasus region? Is it available in electronic form somewhere? It's just that I live in a provincial city far from both of our capitals, and therefore I assume that it will be very difficult to get such a determinant in the form of a book here.

Well, I took the photos, but not very successful, but oh well. Here's what my ground beetle looks like, top and bottom:

Definitely, this is not a Carabus...
It resembles Deltomerus in appearance... Paws on top with hairs?
By the way, what kind of camera was used?

There is no determinant for ground beetles of the Caucasus, there are only a number of works on individual groups. You can still try to run it through the "Determinant of insects of the European part of the USSR", vol. 2.
You can also try your luck with this determinant:
http://www.zin.ru/animalia/Coleoptera/rus/isaev022.htm
You can also try to ask A. S. Zamotailov for advice (http://www.zin.ru/ANIMALIA/COLEOPTERA/RUS/zamotajl.htm)

The camera is a Canon PowerShot A510 3.2 megapixel. I just wanted to take a picture of a couple of carabuses caught in the same place as the ground beetle already presented in the photo, but, damn, the batteries suddenly ran out... Now you will have to wait for them to charge

No, there are no hairs on top of the paw, just a few stiff bristles on the tops of the segments. But there are plenty of hairs on the bottom of the foot. I tried to identify the ground beetle with the help of the identification of insects of the European part of the USSR, but I couldn't. Moreover, I read the description for almost every genus listed in this guide, and if it did not obviously exclude my ground beetle from belonging to this genus, I read the description of all the species included in this genus. Unfortunately, I didn't find my ground beetle there in this way either, although I don't rule out that I just didn't have enough care...
Thank you for your advice, I will try to run the ground beetle by the Isaev determinant, and if this does not help, I will probably have to soap A. S. Zamotailov with a request for help. Photos of other Dombai ground beetles (probably karabus) I'll post it as soon as the batteries are charged, maybe someone will recognize them.

I post, as promised, photos of Dombay carabuses: two of them show the same ground beetle, taken with and without flash; another photo shows another ground beetle caught on the same rocky platform as the first, also under a flat stone. The size of the first ground beetle is 18 mm, excluding 2 mm mandibles; the size of the second ground beetle is 23 mm, excluding 1.5 mm mandibles. Let me remind you that both of them were caught at an altitude of 3200 meters above sea level, in July of this year. Maybe someone familiar with the mountain entomofauna can help me find out who I caught?

Well, the first Procechenochilus heydenianus - 70 percent, and the second... it is not very clear (I also do not have a clear determinant) most likely Pachycarabus koenigi - if it has a greenish border along the edge of the elytra, or Megodontus aurolimbatus, if the border is purple-red-golden, going on the chest.

Nilson, thank you so much! As for the first ground beetle, it looks like it's Pachycarabus koenigi - I found a picture of it on zin.ru, everything coincides, up to the microsculpture of the elytra and pronotum. The band on the edge of the elytra is indeed greenish. The size also matches.
But about Procechenochilus heydenianus, I would like to ask you: is the color of this species so variable? Just click on photos that are presented on the ZIN website Procechenochilus heydenianus has an almost monochrome black color, and mine, as can be seen in the photo in my previous post, has an iridescent colored border on the edges of the elytra and pronotum. In addition, my Procechenochilus has 3 rows of dots on each ndcr, and the Procechenochilus presented on the ZIN website has a ndcr. just evenly furrowed. But the belonging to the genus Procechenochilus is at least obvious
