Stratiomydae

But yesterday was no water, only in some points was a low level of water. In one of these points was floating, dead, this pretty Stratiomydae, with a size of 4-5 mm (bigger than Nemotelus). The place is the same: Pe?aflor, Aragon, Spain. Due to the water, the wing venation maybe is not much well seen, but I hope that can be enough to identify it. Thanks

Nemotelus is not an easy genus - there are 30 species in Europe; the colouration is different between males and females; and even within the same sex, the pattern can vary enormously. Keep posting the pictures, though - and collect specimens! Tony ---------- Tony Irwin

No more than this female yesterday, it was double size and different coloration and I thinked that was a different genus. My knowlegde about Diptera is increasing here! Thanks everybody!!!!!
