Unfortunately it don't let me. So, maybe the genus can't be recognizable, but I try it. Two days ago. Anz?nigo, Huesca, NE Spain, 600 meters. Small: about 7 mm long (without proboscis). Can be identified? Thanks. Regards Edited by Isidro on 23-07-2008 10:43

Dischitus- head broader, laterotergite bare, r-m well beyond m-cu Systoechus- head nattower than thorax, laterotergite haired, r-m and m-cu at same level. biro and senex are pale grey species, the common Systoechus is a yellow fly (usually-they can fade)
