Robber Fly from Antioch Dunes Wildlife Refuge - Stenopogon breviusculoides - male

Robber Fly from Antioch Dunes Wildlife Refuge - Stenopogon breviusculoides - Male
Antioch, CA, Contra Costa County
September 16, 2012
Size: 1 1/2 inches
I was helping with the Lange's Metalmark survey out at the Refuge. My interest in Robber Flies is growing. I know there are unique endemics to the Refuge...also one that is known to be extinct. I'd never seen one this color before.

Is this the only light brown robber fly in the area, or are you keying in on other features visible here?
