Syrphidae fly - Sericomyia chrysotoxoides - Female

There were as many as seven species of flies plus some solitary bees in each head of Queen-Anne's-Lace, never saw anything like this before. It is a little smaller than 1 cm. long. I hope that somebody can help me with the ID.

Moved from Sericomyia. Matches Sericomyia chrysotoxoides image at Canadian National Collection, Sericomyia images plate 2.

Possibly/probably Serciomyia chrysotoxum
Insects of Cedar Creek has a great page on syrphids. I can sometimes find stuff just by browsing through the images of various genera.

Sericomyia, esp. S. chrysotoxum looks very good for your image. Disclaimer: I'm totally an amateur--I just am looking at patterns. However, the antennae, pubescence, etc. look real close on that one.

Sericomyia chrysotoxoides
I think the Cedar Creek image of Sericomyia "chrysotoxum" is mislabeled: it should read S. chrysotoxoides. They probably were thinking of the syrphid genus Chrysotoxum when they labeled it, as there is no North American flower fly having "chrysotoxum" as its species name. I have a photo that matches your image, and it was IDed as S. chrysotoxoides by an Entomologist in Ottawa.
