Dear collegues
I do not even know the order of this grub, maybe it is a beetle?
I found it in a humid forest on the lower surface of a foil of a plant, I think it was Lycopus europaeus.
On the back end it carries the covers of the last instars?
Germany, Lower Bavaria, 2016-07-03; 450m over sea level.
Thank you very much for your help!
