Earthworm reproduction is a lot more complicated than anyone might suspect. Especially since earthworms are hermaphrodites. A hermaphrodite possesses the ability to produce both male and female cells, meaning they produce both sperm and eggs. Usually, an animal which is a hermaphrodite, is able to reproduce within themselves, without the need of assistance from others.
But earthworm production is quite different. Even though an earthworm has male and female sex organs, they need another worm to reproduce. When two earthworms do mate they release sperm to one another. Each earthworm actually has two sperm receptacles, so each receives two exchanges of sperms.
Temperatures must be just right for earthworm reproduction. The ideal is around fifty-five degrees, allowing earthworms to mate in the spring or fall. Earthworms cannot see or hear but know that another worm is present by ground vibrations. Sometimes they literally bump into one another. Very often worms live beside one another in burrows so another worm is often close by.
Usually mating in earthworms happens after a rain when the ground surface is wet. While some worms do travel to find one another, others simply stick their behinds, or anterior portions, out of their burrows. Mating is accomplished through the joining of this portion of their bodies, which remains connected while the earthworm's heads are pointed in opposing directions.
