Hey Dominik.
Thanks for the suggestion... I had meant to check this out sooner but forgot.
I'll check it out.

Fyn, did you check this one?

Fyn, if you could not get down to species level, than it should be something special! Now, I know why. Tricky one and I am not sure, if my arguments can convince you ;-)...
The first I checked was Calligrapha multipunctata, which, however, has a white part on the head:

I think you would agree, that it is one of the Philadelphia group:

Vicina has in my eyes much stronger markings than Philadelphica and there is one marking which is seen in all Vicina, but not in yours and in almost all Philadelphica: between the median line and the shorter lateral line, there is a strong "shortened" u-like marking. That make me think of Calligrapha philadelphica. What do you think?

Thanks Rieko!
