Help us identify a beetle from Karelia. In case of danger, he pretends to be dead. Karelia, on a stalk of onion.

Not Bradytus, it seems to me. Try a different subgenus.

Dear experts,
please help me identify these snappers.
I know that some of these fees have been assigned to me here quite recently, but these are different fees and come from different places, so I'm a little doubtful. In any case, I am aware that these are not very good scans, so in complex cases, as always, up to rod.

Thank you very much

Thank you.
So, it's good that I put on the definition of species that I had previously defined, because there was even more confusion.

Here, dear Elizar gives me the definition of 4,5,12 as Melanotus castanipes, but the same as 12 and 4 I was defined here as Melanotus rufipes. Who is it really? At the same time, No. 5 is very different in color. It is all black, like soot from diesel fuel and PRSP black. Is it still a beetle of the same species as 4 and 12 or not?

According to number 10, at first I had no doubt that this is one kind. Well, you never know why one is smaller than the other wall.gif, but they still have differences, one of them has a black PRG from below, and the other is red. Does this happen? Should I scan these friends from below?

Thanks

With apologies and thanks
Ira

By numbers 10 - many beetles have males smaller than females. And in general, in some groups there is a spread of body size in 1.5-2 times. This depends on how well the larva ate.
And numbers 4 and 5 are clearly of the same type (especially if they come from the same sample). Color is unreliable and changeable.

Take a picture in Rostov-on-Don on May 23.
The size is about 1 cm. Apparently, Anthophilus is a pollen eater

Dear experts,
I ask for help in identifying these two barbels, 9 mm and 17 mm long from the Moscow Region.

Thanks

I get one that is smaller than Paracorymbia maculicornis (Degeer, 1775)

The first barbel is Stictoleptura maculicornis Deg.

Irina turned out to be more correct than the respected scaritwink.gif-the first barbel, of course, is Paracorymbia maculicornis (De Geer, 1775).
The second is Lepturalia nigripes (De Geer, 1775).

Although, it's all about the modern interpretation of childbirth. I like old Jacobson. It gave rise to Leptura maculicornis. Then I threw this phrase in Yandex and there I chose a modern interpretation of the genus by ZIN. And the whole story jump.gif

Gravediggers of this complex (smooth without pubescence prsp., and the mace of the antennae is partially yellow-red) should look from below at the color of the hairs on the abdomen
there can be 3 species, rather it is N.fossor all abdominal sternites in yellow hairs.

The first gravedigger with a wide front sling is habitually very similar to the investigator, which is generally extremely interesting. And the rest are really similar to interruptus (=fossor), but it is advisable to check for sepultor. Are they all from the same point?

Yes, sometimes I got it from one trap.

E. A. Khachikov lowered the rank of interruptus to the subspecies of investigator by the structure of the endophallus. And here it comes out-different subspecies fall into one jar)

Does the first beetle have a dark spot on the epipleura at the base of the ndcr, or is it just a shadow? I don't understand something.

29.12.2010 22:41, Fornax13

Not Bradytus, it seems to me. Try a different subgenus.

A. brunnea has never been anything like a bradythus. She's from Celia, as I recall. And the beetle is very similar to her, by the way.

There is a spot, I've dealt with the epiplevs. I also tried to take a picture of him, and the photo of another gravedigger, I think Germanicus, was caught in the same place as the previous one.
