Promachus
There is a group of white-tailed species. So we might have to go with White-tailed Bastard for the name. Nice shot. The only other species in WI is the P. fitchii which is very different in coloration.

White-Tailed ???
Thank you for your comments. If you find another species that is named White-Tailed Robber Fly, please let me know. White-Tailed Bastard sounds too crude for me. :-))
