Syrphid Fly: Eristalis? - Eristalis tenax - female

Syrphid Fly: Eristalis? - Eristalis tenax - Female
Fisher, Polk County, Minnesota, USA
November 6, 2010
Size: Length ~ 10-12 mm
Insect life is scarce at this prairie latitude, this time of year. I haven't seen a syrphid fly for weeks until recent high temperatures soared into the mid-50s. This specimen was found sunning itself on a south-facing brick wall. It's much darker than our usual syrphid flies, so I'm hoping there's enough detail in this image to identify to species. My best guess is that it may in the genus 'Eristalis'. But I could be wrong about that. Hoping for help with identification. Thanks! ;-)

Eristalis does look right.
Marked a lot like Eristalis dimidiata, but this one is a lot more hairy. Species ID is beyond me and not given for many of this genera here.

Eristalis tenax?
You're right, Ron. This specimen seems a bit too hairy for 'E. dimidata'! I wonder if it might resemble 'E. tenax'? I found a couple of BG images of tenax that look interesting. What about this image? http://bugguide.net/node/view/34526

Sorry for the delay, Carl.
Also sorry this doesn't appear to be the same fly. In my experience, E. tenax is more orange/brown, than yours, tho there is apparently some variation.

Okay!
Thanks for your help with this, Ron! ;-)
