Drosophila pseudoobscura is a species of fruit fly, used extensively in lab studies of speciation.

In 2005, D. pseudoobscura was the second Drosophila species to have its genome sequenced, after the model organism Drosophila melanogaster.[2]

Diane Dodd was able to show allopatric speciation by reproductive isolation in D. pseudoobscura after only eight generations using different food types, starch and maltose.[3] Dodd's experiment has been easy for many others to replicate, including with other kinds of fruit flies and foods.[4]
