Braulidae, or bee lice, is a family of true flies (Diptera) with seven species in two genera, Braula and Megabraula.

Similar in appearance but not closely related to keds, these flies are also small, wingless, and occasionally mistaken[2] for mites or lice, hence their common name.

The first discovery of Braulidae was of Braula coeca, in 1818 by Christian Ludwig Nitzch, a German zoologist.

Many species of Braulidae are thought to have different host honey bee races.

B. coeca is the most widely known Braulidae species, most commonly seen on honey bees around the world.

Once the adults become mature, their eggs are laid on honey bee wax cappings.
