Why are these frassed?
Do we have better pixs from Colorado?

Criorhina sp.
Neat find! Sure looks to me like a species of Criorhina, some of which are enormous bumble bee mimics. Family is indeed Syrphidae.

 
Criorhina?
Thanks, Eric. Have to look a little further. What I can google, doesnt show the same venation. The only Criorhina in Colorado is C. oxyacanthae which this one is not. It looks like E. burda.

 
Arctophila flagrans?
Now that one of my photos has been identified as A. flagrans, I notice that this picture looks very similar to me.

 
Ok.
Wow, at first blush it sure looks like Criorhina, but I trust your sources:-)

 
Ciorhina sp?
