When first observed in a new region, D. suzukii has often been confused with the western cherry fruit fly (Rhagoletis indifferens) and was given the short-lasting name cherry vinegar fly.[14] The cherry fruit fly is significantly larger than D. suzukii (up to 5 mm) and has a pattern of dark bands on its wings instead of the telltale spot of D. suzukii. The telltale spots on the wings of male D. suzukii have earned it the common name "spotted wing drosophila" (SWD).
