Drosophila hydei

Description

Drosophila hydei is a species of Diptera, or the order of flies, in the family Drosophilidae. It is a species in the hydei species subgroup, a group in the repleta species group. Bizarrely, it is also known for having approximately 23 mm long sperm, 10 times the length of the male's body. The name derives from Dr R. R. Hyde, who first discovered that the species was distinct from Drosophila repleta. Hydei are one of the more popular flies used as feeders in the pet trade. A few varieties are available, some flightless.
