Hi Steve and others:
The images of "Sericomyia chrysotoxoides" do look quite close to yours. I 
note the (hairy?) posterior band on yours (which appears to be a 
orange/yellow) is not on the "Bug Guide" images. What about the fuzzy/hairy 
ring just behind the eyes on yours...also not on the Bug Guide ones. Likely 
there is enough variability to account for those diffferences.
I found a Hover Fly a few days ago in several locations that I have yet to 
identify on Bug Guide. Will keep searching....
