Drosophila hydei
Hydei Fruit Fly
Drosophila hydei is a vinegar fly in the family Drosophilidae, notable for possessing the largest recorded sperm of any Drosophila species at approximately 23 mm—over ten times the male body length. It is a member of the hydei species subgroup within the repleta species group. The species is widely used as a feeder insect in the pet trade and has contributed significantly to invertebrate genetics research through the Minos transposon, which has been developed into a versatile genetic tool for gene disruption across diverse arthropod genomes.
