I have photographed the following fly which is iridescent green in Pittsburgh, PA. I guess it was about 0.5-1.5cm long.

Can you help me to identify it?

Thank you for making your photo available as Creative Commons. I use many CC-licensed photo in my classes. Perhaps I will one day use yours. – Mike Taylor Aug 8 '14 at 21:31
@moose Iridescent is probably the word you are looking for. – Drew Aug 8 '14 at 21:32
It's a blowfly. They sometimes ruin my compost heaps (the larvae). – J. Musser Aug 9 '14 at 1:43

Looks like a green bottle fly.

Might be a Common Green bottle fly.
