Xylota or Chalcosyrphus - Bill probably will have a better idea than I.

Chalcosyrphus species with two pairs of maculae on the abdomen like this fly include C. anthreas (possible), C. metallicus (feels more correct given the pale front legs), and C. nemorum (this fly is too pale esp. in the legs for C. nemorum); all three are in range.

 
The hind femora are more infl
The hind femora are more inflated in Chalcosyrphus and I would say this was Xylota. I have sent it to Martin for his opinion. Chalcosyrphus anthreas and nemorum have some black on the front and middle tibia and Chalcosyrphus metallicus has the front and middle femora mainly orange.
Maybe Xylota quadrimaculata...... male

Ah! I'd always wondered why they keyed out in a different place in the genus key, and the hind femora issue explains it. Thanks! (it did feel more like Xylota but I don't have as much info on them as I do on Chalcosyrphus)
