Hi J?rgen,

But look this male Eristalis tenax http://www.dipter...d_id=11255 which I posted from exactly the same area. They look so different. Shock

This Eristalis has much lighter coloration, less hairy and distinct yellow knees. The one from December was very dark which almost no yellow in the knees.
Could it be Isael has two sub sp. or this variation are acceptable?

Tenax is very variable in coloration, but somehow always easy to recognize...
