Drosophila hemipeza was listed as federally endangered in 2006 along with ten other species of picture-wing
Drosophila. Threats to the conservation of
D. hemipeza include loss-of-habitat, in part due to invasive pigs and rats, as well as introduced predators such as
yellowjacket wasps. Invasive plants such as
Psidium cattleianum also threaten the conservation of
D. differens by overwhelming native species and outcompete them for access to light. On Molokai, non-native
axis deer threaten native ecosystems by trampling and overgrazing native plants. == References ==
