Hello!

Unfortunately I had to use the flash here, and so there are more reflections visible than wing venation :|. Is this 9 mm fly from our garden yesterday (northwest Germany) a male Phaonia? Or possibly Muscina stabulans? (I see no "wave" in vein M, but I hardly see anything...)

Hi Juergen
I know I'm the last one to be determining flies, but I had one the same or similar a couple of days ago which Stephane Lebrun thought was M.stabulans till he realised it had hairy eyes then changed it to P.errans. Don't know if the species is the same...but Phaonia I think with those hairy eyes. Probably wrong AGAIN :|.
Regards Roger

And on your specimen the M vein was not visible, here it is visible and straight so not Muscina without doubt.
Indeed it is a male Phaonia, and if really only one pair of prescutelar acrostichal setae is present, I would say Phaonia tuguriorum.

Hello, Roger and Stephane!

Thanks for your replies!



Arrghh, they are back... ;) In the colder season I always hope to find some other Phaonia than tuguriorum. But I should have been warned: the females already were numerous in our garden again last week (although much less blue and distinctive).
