Thank you in advance.

Thanks! Hycleus -- very similar, but I looked at the pictures on the Web, my beetle didn't have spots all over its back. Thanks for that too

can there be such a picta?

Alexey! This is not picta! Please specify the size!

Hi, everybody

Is it possible to identify a beetle without a photo? a very common animal, a small bug, about 3 mm long. Elytra with a metallic sheen, green or blue. pronotum is light brown or orange. we used to call them "fireflies" when we were kids, but now we're just wondering who they really are...

Gastrophysa polygoni, RSA?

Please help us determine the type of beetle:
It is not more than a centimeter and therefore the photoaparate could not clearly shoot. The top is dark blue (almost black), and the bottom is dark purple.

I hope that someone else comes here...
I found here in this topic a photo of the larvae of a soft-bodied beetle. I think I found something similar for a couple of days at my dacha (Krasnodar Territory, Gelendzhik). What do you think he is? And if it is, which one is it? Because in my photo it is clearly darker...
P.S. this is it on the apple core sitting )))
Thank you.

Chrysolina sturmi Westhoff, 1882 similar? But the photo would be bigger and sharper. It's hard to say for sure.

I think it's him. Very similar.
This is the best photo I've ever seen...
Thanks!

The photo is extremely unclear, so it is far from a fact that this is a Chrysolina sturmi. It should be possible to use the determinant to drive by keys. Maybe it's something like Chrysolina carpatica or something close to it. Isn't Uzhgorod listed on the label? By the way, does the beetle have wings? If not, it's definitely not sturmi.

Tell me, please, correctly defined Chrysolina variants (Schall.) dl. 5,5-5,7 mm.
