Robber Flies

Fly Identification
Location:  Greeneville, TN

I encountered these in northeast TN (Greeneville) in the middle and end of August. The closest thing I can find to this bug online is a stiletto fly or a golden-haired robber fly. While visiting an area of predominantly farmland and woods, I found these everywhere. They were attracted to my bike as I rode through rural areas. The locals I stayed with didn’t recognize them either, so I’m not sure if they appear regularly or not. Thank you for your help!

Hi Jennifer,
You are correct about this being a Robber Fly, but you have the wrong species.  We received so many identification requests for the Red Footed Cannibalfly,
Promachus rufipes, in late July that we made it our Bug of the Month for August.  We continued to get identification requests in August, so we suspect that the species was especially common this year.  Insects often go through cycles when their numbers diminish and then surge.
