Large Hoverfly.... - Tropidia quadrata

Large Hoverfly.... - Tropidia quadrata
Edmonton, Alberta, Canada
July 3, 2008
This thing scared me. It kept rotating so it always faced me, something that dragonflies sometimes do.

Moved from Tropidia.

After second look
Is it more likely Eristalinae, Milesiini, and to be more precise Tropidia sp., probably T. quadrata!
From this angle it looks like Xylotini, but the face and the colors are slightly different from that!

Gerard, might this also be T. quadrata?

This one was much larger than that one so I don't think it could be.

Syrphidae, Xylotini
Xylota or Chalcosyrphus!

How could we narrow it down?
I can still vaguely remember what it looked like.

Apparently, ID to tribe is as good as it gets.
Suggest you move it Xylotini.

All I can say here it it's a male.
If you're browsing to get an ID here, note the meaty back legs. Wish I could be of more help.
