Caption: Dragonfly, hamulus, scanning electron micrograph (SEM). Mating in dragonflies is unique. The male testes are located in segment nine. Due to the unique nature of dragonfly copulation, the male must transfer sperm to his secondary genitalia, called the hamulus, located in the underside of the second and third segments. The hamulus is a complicated set of "surgical tools" that the male uses for removing the sperm of other males from previous matings. Other parts of the hamulus are then used by the male to fertilize the female with his own sperm. Magnification: x23 when printed at 10 centimetres wide.
