Fly
Looks like Drosophila melanogaster.

 
immigrans?
The dark spots on the veins would make it immigrans more likely than melanogaster.

 
Drosophila I.D.
I agree it looks like a D. immigrans because of the dark cross-veins and dark spots at the ends of each vein (D. melanogaster has clear wings). The abdominal pattern also indicates it is not D. melanogaster (D. melanogaster has posterior bands on each tergite that are unbroken, this specimen seems to have the triangular posterior bands on each tergite that are broken down the midline as in D. immigrans).

 
Size
I don't know if this is pertinent, but these seemed larger than the laboratory fruit flies I've worked with.
