Chalcosyrphus curvaria - Chalcosyrphus curvarius - female

Chalcosyrphus curvaria - Chalcosyrphus curvarius - Female
Flower Station, Lanark, Ontario, Canada
July 25, 2009
Size: 20mm
This fly was moving about on fabric surfaces - on a pant leg, then onto a backpack, then onto camera bag. I believe it is Chalcosyrphus curvaria as it looks identical to an image of that species in Stephen Marshall's "Insects: Their Natural History and Diversity".

Moved
Moved from Chalcosyrphus.

Either Chalcosyrphus curvaria
Either Chalcosyrphus curvaria (if hind coxae are entirely black and halteres yellow) or C. plesia (if hind coxae have a small bit of orange and halteres are brown). I can't see enough detail to tell between the two.
