This is an interesting article on how the Med Fruit Fly was introduced into California and the U.S.:

Here's a little info on the 'smaller' house flies from:
Fly Control - Flies, Drain Flies, Cluster Flies, Flys, House Flies, Black Flys, Fruit Flies
Little House Flies and Latrine Flies
Biology:
These flies usually appear in the early spring before the house fly has become numerous. These species are smaller that the house fly, more slender in appearance and the fourth vein extends directly to the edge of the wing instead of curving sharply upward as in the house fly. Eggs are laid in animal excrement and decaying vegetation and sometime in vats in cheese plants. The little house fly is frequently seen hovering in midair or darting about in the middle of a room. It differs from the house in that it is found throughout the house and very seldom on a spread table. This species lays it eggs on decaying vegetable matter and excrement, particularly of chickens, human, horses and cows. The larvae emerge in about 24 hours and may be recognized as a flattened, spiny organism about 6 mm long when full-grown. The pupal period lasts about 7 days under favorable conditions. The complete life cycle last 15 to 30 days. The Latrine fly, is very similar to the little house fly, but the latrine fly adult is slightly larger. Its biology and habits are also the same.
VERY INTERESTING - IS CHICAGO NEXT?
Fruit flies out of control in September in Chicago, in the resturants and sewer pipes?????
Florian flushes fruit fly infestation - The Chicago Maroon
What's the name of those black, flying 'snit' bugs that hang around sewage, sewer pipes, or septic tank pipes - I'm thinking this might be closer to the culprit?
(We need to look at Jo's 'Orange Fly'... since she's positively identified her sample.)
