Adactylidium is a genus of mites known for its unusual life cycle. The pregnant female mite feeds upon a single egg of a thrips, growing five to eight female offspring and one male in her body. The single male mite mates with all the daughters when they are still in the mother. The females, now impregnated, eat their way out of their mother's body so that they can emerge to find new thrips eggs. The male emerges as well, but does not look for food or new mates, and dies after a few hours. The females die at the age of four days, when their own offspring eat them alive from the inside.
