Aphid eater on milkweed. Puparium - Eupeodes

Aphid eater on milkweed. Puparium - Eupeodes
Schuylkill Nature Center, Philadelphia County, Pennsylvania, USA
November 18, 2009
Size: 8 mm
It pupated yesterday. From now on I am keeping it indoors because I want to see the adult for ID purposes. I don't know if syrphids overwinter as larvae or puparia and don't want to take that chance.
Update: apparently many syrphids overwinter as larvae. However it is possible to find adults in February (in the Washington DC area).

Lovely puparium
