What is "braula"

Braula is a genus of flies (Diptera) in the family Braulidae or bee lice. These are very unusual flies, wingless and flattened, and barely recognizable as Diptera. Braula coeca Nitzsch is a pest of honey bees. The larvae tunnel through the wax honeycomb and the adults are found on the bodies of honey bees. There is some debate as to whether the bee louse causes damage to the honey bee. These flies sometimes can be found at places where bees congregate such as flowers or salt licks, waiting to grab onto hosts from uninfested nests. Braula is cosmopolitan and about 1.6 mm in length.
