Istochaeta or Baumhaueria. Not closely related, but surprising similar on picture. Date strongly suggests Baumhaueria.

Very rare species in central Europe !

Thanks. What rally would help, is a picture of the thorax dorsolateral, and then please the right side, since the left side is destroyed by the pin.

So, it is the male of Istochaeta cinerea.
On the wing from end of April till begin of June, hence my initial doubts.

It is a very rare species in central Europe, so excellent find !

All Istochaeta are parasitoids of Melolonthinae, Rhizotrogus, Amphimallon and so on.

Outside of Europe, some other scarab beetles are parasitized. In America we have I. aldrichi imported from Japan to attack the "Japanese Beetle" Popillia japonica.
