Is this another case of a fungus growing off the body of an insect?
The fly was at the very top of the aster plant, and its abdomen seems to be bursting with some kind of growth.

Entomophthora?
This looks like and Entomophthora infection. Another question: Are you sure this is Syritta? The hind legs look too small and the (visible) markings on the abdomen too yellow.

Toxomerus
Oops! How careless of me! Of course you are right; thank you for pointing this. The pattern of the abdomen shows very clearly in another photo and it is Toxomerus geminatus. Thanks.

Dead or alive?
This one almost looks alive. Was it dead? I see what you're talking about and it definitely looks strange.

 
Dead fly
It was very much dead, it didn't move for hours.
