; order Diptera, suborder Cyclorrapha)
Family of abnormal flies which lack wings and resemble members of the Hippoboscidae. The antennae are set in lateral grooves, and the eyes are reduced in size. The thorax appears to be joined to the abdomen. The tarsi are adapted to cling to the bodies of Hymenoptera, especially bees. Bee lice eggs are laid near honey- or pollen-storage cells inside a bee nest, and the larvae feed on these substances and pupate within the nest of the host. The pupa is unique among the Cyclorrapha in being enclosed in the unmodified last (final instar) larval cuticle. There are eight species in two genera (Braula and Megabraula).
