Mydas flies
Mydas is a genus of flies in the family Mydidae, established by Fabricius in 1794. These are among the largest flies in North America, with some species reaching substantial body lengths. The genus is characterized by elongate clubbed antennae and wasp-mimicking coloration, typically featuring black bodies with orange or red markings. Mydas flies are often mistaken for large wasps or robber flies by observers due to their impressive size and similar appearance to hymenopteran mimics.
