Mydas Fly

Amongst a large group of honey bees this fly was a very active and ambitious feeder.

The Mydidae (alternative spelling Mydaidae), or Mydas flies, are a cosmopolitan family of flies. It is a small family, with about 471 species described. They are generally large in size, including the largest known fly, Gauromydas heros (syn. Mydas heros). Many of the species, in addition to their large size, are mimics of stinging hymenopterans, especially wasps. Most mydids are found in arid and semiarid regions of the world, but they are also found in other habitats.
