Braulidae
Braulidae, or bee lice, is a family of flies ( Diptera) with eight species in two genera, Braula and Megabraula. These are most unusual flies, wingless and small, and barely recognizable as Diptera as they have the superficial appearance of mites or lice. They have reduced eyes and antennae hidden in grooves. Their legs are short and robust, while the claws are equipped with minute teeth. Their life-cycle is intimately connected with that of bees, particularly queens and drones. The adults are nimble and scramble for food being fed to the queen. The larvae feed on wax and pollen.
