These usually turn out to be Ceriini (Syrphidae), but I can't reliably tell them apart from some Conopinae.

 
Knowing enough to be dangerous.
I'm pretty sure this is a syrphid; check the other image for slightly clearer venation. Now I get on shakier ground, separating Ceriini from Conopinae. Doesn't the former have longer antennae - and the latter more of a wasp waist?

This one looks very familiar, but I can't quite place it. Maybe later.

 
Ceriini?
