High Adaptability Allows Invasive Fruit Fly to Thrive in New Environments
Drosophila suzukii , commonly called the spotted wing drosophila or SWD , is a fruit fly. Native to southeast Asia, D. Like other members of the Drosophilidae, D. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing.

It can directly infest the fruit of many plants, but is most attracted to raspberries, blackberries, blueberries, and other late-season, soft-flesh fruits — cultivated and wild. SWD deserves notice because, unlike her relatives, which lay eggs on over-ripe or rotting fruit, she can lay eggs inside fresh fruit, often before harvest. After only a few days, the fruit skin becomes dimpled or wrinkled, forming craters in the fruit.
