I was last week in the gypsum caves in the Ternopil region. The total length of the cave passages is more than 50 km. Asked to watch beetles in the cave, found only one. but also, as I understand it, not caveman. Found more than 500 m from the entrance. What a group, in my complete ignorance of beetles. I think it's a small black-skinned thing. Is the view interesting? accidentally wandered or still tends to caves. the quality of the photo is no good, in a hurry 4-5 mm. If it's interesting, I'll retake it better. (I'll try to reshoot it.)

I'm afraid to make a mistake, but it looks like Xylotrechus clarinus.

As far as I know, X. clarinus is only found in Sakhalin and the Kuril Islands in Russia. Imho, still X. ibex.

Dear friends! Tell me what kind of carabus. For me, so Carabus (Megodontus) vietinghoffi. Gathering point, southernmost Korea, Jeju Island. I apologize for the photo, but, so far, only this.

In the park of St. Petersburg, yesterday. 5 mm.

It's hard to say right away, but definitely not vietinghoffi. The sculpture of nadkr is completely different.

Perhaps Carabus (Eucarabus) arvensis? I do not know what subspecies can live on Jeju Island. Confused by the size-28 mm.

Not a butterfly, but flying. And he runs - very fast. I suspect that it can also swim. ??????
Bryansk province, Apr. Mercy, pliz.

from larvae from tinder boxes found on birch trees, I brought out such beetles (tell me the type?) some are still in pupae (of varying degrees of maturity), one has horns on its head, the other does not (left photo). I didn't notice any other differences from pupae without horns. Is it a different species or an atavism or something else?

Can you identify copra from Laos from these photos? Large-32mm.

Rogachik from the South. Sulawevi. Dl. - 15mm

It looks like a carabida. Laos. Dl. - 18mm

Ruteline from Vietnam. Length-24mm

Maybe someone can tell you who is in the picture?

Almost certainly Telotoma hayesi (Hope, 1833), male. Endemic to Príncipe. It should be very large (80-125mm).

Possibly an undyed female Neomida (= Oplocephala) haemorrhoidalis (F., 1787)
The male is the one with the horns.
Before the photo was taken, how long ago did the beetle hatch? It's just that no one else comes to mind

Place of capture Sabah Malaysia

maybe a day or two, there are still quite white ones

Xixuthrus microcerus bufo (Thomson, 1878), female.

Is there any way to identify the bronzes from South Asia?
