Drosophila digressa is an endangered species of fly from Hawaii, in the species-rich lineage of Hawaiian Drosophilidae.

[2] It was historically known from sites throughout the islands, but is now restricted to the Manuka and Ola'a reserves.

The wings have brown markings on crossveins and at the apex that are characteristic for the species.

D. digressa was originally difficult to place within the picture-wing clade,[4] but phylogenetic studies indicate that it is part of lanaiensis subgroup, along with D. hexachaetae, D. moli, and D.

[3] Threats to the conservation of D. digressa include loss of breeding habitat, and predation from introduced insects such as yellowjacket wasps.
