Syrphid pupa development 5-29-08 - Syrphus - Male
Churchville Nature Center, Bucks County, Pennsylvania, USA
May 29, 2008
Size: About 10 mm.
Syrphus, Eupeodes? Any help will be greatly appreciated as I am very bad at IDying these flies. Also, it would be great to know the ID of its larva.

Syrphid maggot
Thank you for the lifecycle images. Found a maggot eating black aphids on Canada Thistle (Cirsium arvense) today. Syrphus also found here.

Moved
Moved from Syrphini.

Moved from Syrphid Flies.

For the adult
Assuming this is in the SF: Syrphinae and as you have the specimen it should be easy to decide whether this is Syrphus or another genus:
Lower lobe of calypter with many coarse yellow hairs above . . . . Syrphus
Lower lobe of calypter with only microscopic pile above, or, rarely, with a very few fine pale scattered erect hairs . . . . . other genera (many).

 
Thanks Tony
Please, see the image that I added, I hope that you can figure it out.
