There are a few varieties of flightless (vestigial) fruit flies (turkish gliders, curly wings, etc.) and wingless (apterous) fruit flies (standard, golden delicious, etc.). There was a good article online that documented all of the Drosophila species & strains which are commonly cultured in the hobby but unfortunately it is no longer online.

I currently keep turkish gliders and standard wingless, and the turkish glider cultures are more productive for me than the wingless. Could just be me but I've heard some others with the same experience. They hop around but are also easily contained and worth it.
