Scaptomyza is a genus of vinegar flies, insects in the family Drosophilidae.

[8] The "single Hawaiian origin" hypothesis suggests that the common ancestor of Scaptomyza and Hawaiian Drosophila colonized Hawaii once, followed by several migrations to the mainland within Scaptomyza.

[8] One member of the genus in particular, S. flava, is studied as a laboratory model organism for herbivory and the evolution of plant-insect interactions.

[11] One specimen, assigned to the species S. dominicana, has been described from Dominican amber that is estimated to have been deposited at least 23 million years ago.
