How to identify SWD

Identifying Spotted Wing Drosophila

Spotted Wing Drosophila (Drosophila suzukii), looks like its fruit fly relative, the common fruit fly (Drosophila melanogaster) but there are some distinctive characteristics that are specific to spotted wing drosophila (SWD).

 

Drosophila larvae cannot be identified to species. Only adults are identifiable. Most of these characteristics can be seen with the naked eye, but a hand lens is useful.

 

Our video aims to help explain how to more easily identify SWD:

The males have a large spot along the front edge of each wing and it also has two dark sex combs on the forelegs.

 

 

 

 

 

 

 

 

 

 

 

 

 

The female can be recognised by its unusual serrated ovipositor which allows it to penetrate the skin of fruit.
