Mating occurs when the male deposits a sperm packet in the female.

This sperm packet inhibits the female from further mating.

These modified legs, which are usually on the seventh segment, are used to transfer sperm packets to the female during copulation.

Eventually, the female will open her genital slit, located between her own pectens, and aspirate up the sperm packet.

The female takes up the sperm packet by grasping it with the lips of the cloaca and pushing it into the vent.

The sperm packet inserted into the female constitutes about 60% of the males' body weight.

A spermatophore is a sperm packet used by invertebrates.

He puts a sperm packet into the female by guiding her over him using his front legs.

As he reaches out with the sperm packet, he displays a pulsating pattern.

This gland produces the spermatophore, which carries a sperm packet at its tip.
