Saw at Ekkeroy, northern Norway, on the beach.

Looks like Coelopa pilipes ?
How can I recognize males from females ?

looks like Coelopa pilipes without long, dense pile on legs, so it is Coelopa frigida. C. frigida is the most frequent one, I think even in Norway. Yours seems to be a small and dark specimen. You can regognise the sex at the tip of the abdomen which is not visible on your picture. I'm tending to male in your case because abdomen seems to be short and rounded but I'm not completely sure.

Thanks a lot for the clarifications. I thought Coelopa frigida had stronger spines on the legs.
Thanks for the details on the sex as well (I don't have a photo of the apex of the abdomen).

Coelopa frigida is for a fly extremely polymorph depending on its size. Larger specimen tending to have more and larger spines while smaler specimen tending to have to have a small number or nearly none of short spines. Thats the reason why there were described several Coelopa species in the past which are all synonymized with frigida now. In experiments froms were interbreeding.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol
