Hello,
I found this little fly on the plant Verbascum thapsus near a disused railway track. If my photos are precise enough, could it be the genus Silba (Setisquamalonchaea) and even the species Silba fumosa ?
Thank you in advance,
Dominique

It is exactly the kind of circumstances where I see this species in our museum garden every year.

yes this is Silba fumosa - almost entirely black with orange-brown calypteres and fringes
