Drosophila immigrans Sturtevant, 1921
Explanation of Names
When Sturtevant named the species in 1921 he already knew it was found around the world and likely a recent immigrant.
Distinguished from most similar yellow species by the small dark patches at the tips of veins R2+3 and R4+5 and along crossvein dm-cu.
Nearly cosmopolitan. Perhaps introduced from Asia.
Non-native. According to Sturtevant it was first found in the continental United States in 1913 in New York and Massachusetts.
