A specimen resting at a light trap S of Norway 17th May in an oak forest 30 masl. I have filed this as
Bactromyia aurulenta?, but would like to have an opinion if it can be identified. I have two dorsal shots only, at least
Cyzenis could be a pitfall (for me), applying the key of Tschorsnig and Herting. The arista thickening might be a bit too long for
Bactromyia and fitting
Cyzenis better? (Eyes hairy, one oe.)
Any help appreciated, as always!
Cheers Jørn

And one ad on tibia 2 and apical scutellar bristles lacking and wing venation:
I'd say Cyzenis albicans.
