Poecilochirus is a genus of mites in the family Parasitidae. They feed on fly eggs and larva. At least 14 species of the genus are carried from one food source to another by beetles of multiple genera in the family Silphidae with whom they often have a symbiotic relationship in protecting the beetle’s larva or its food supply from fly larva. Reportedly some nematodes in the family Allantonematidae are parasites of mites in this genus.
