Hello,

I compared this fly with Nikita's pictures
( http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=1670 ) and mine doesn't seem to have this dark parts on the femora (Nikita's nailed fly has neither).
Is that of any importance or could it be the same species ?
I saw the animal a week ago, near Heerlen.
