The genus Drosophila is one of the great success stories. There's hundreds of species within the genus. They're on every continent except Antarctica, they're in tropical rain forests, they're in deserts, they've evolved many exotic mating behaviors, and they're capable of incredibly long-distance flights.

Only flies have true halteres. In fact, the scientific term for flies, 'diptera,' means 'two wings.' Most insects, including bees, have two pairs of wings for a total of four. In flies, the hindwing pairs have been transformed through evolution into the halteres.

Although their maneuverability is limited, blind flies can fly remarkably well.
