The film shows, at normal speed and in slow motion, the sexual behaviour of Drosophila virilis. Courtship mainly consists of a rapid stroking with the forelegs at the female's abdomen, of licking at the genitals of the female, and of wing movements. Not only females, but also males are frequently courted. During copulation, the males display some jerky movements.
