Robber Fly - Proctacanthus occidentalis

Robber Fly - Proctacanthus occidentalis
Bessie Butte Summit Trail, Deschutes National Forest, 8 miles southeast of Bend, Deschutes County, Oregon, USA
August 23, 2008
Size: 2"
This Robber Fly was preoccupied, as you can see, with a bee it had captured and was in the process of devouring. So I was able to crawl up to it on my belly and take dozens of photos.

While I was able to determine that it is in the order Asilidae, I found that there are many species of differing characteristics and size. The scientific name for this species would be greatly appreciated.

I especially like this close-up since it shows such details as wing hinges and the familiar "beard." This is one hairy bug!

Nice images!
Minor point in taxonomy - the order is Diptera and the family is Asilidae... We have several experts on this site that will probably be able to ID this fly to the genus level, anyway...

 
Robber Fly (order Diptera, Family Asilidae)
