October 22, 2009
My friends and I do alot of macro pictures of bugs and came across this fly with large green eyes and a metallic green body. Can you tell us what it is?

After unsuccessfully searching BugGuide, we were going to post your photo and enlist help from our readership, but one last ditch effort led us to Ornidia obesa, a species of Syrphid Fly, commonly called Flower Flies or Hover Flies. Seems this species has a somewhat dubious reputation. According to BugGuide: “It breeds in human latrines and other semiliquid wastes” and “It is known to carry bacteria of public health importance (Salmonella, Shigella and Mycobacterium). The species is also beneficial as the maggots can convert coffee-production waste products into useful protein sources for cattle feed.” We found reference that this species from the New World tropics has spread to the Old World Tropics as well.
