The spotted wing drosophila is a vinegar or fruit fly of East Asian origin. It has been in Hawaii since the 1980s, but was first discovered in California in 2008. By 2013, it was reported from most of the continental US, except Arizona, Nevada, New Mexico and South Dakota. It infests raspberries, blueberries, day-neutral strawberries, grapes, cherries, peaches, plums, and other late-season, soft-flesh fruits, both wild and cultivated.
