The family Strashilidae is an extinct group of Jurassic flies from Siberia and China. They were originally believed to represent a distinct order called Nakridletia,[1] but recent research has determined that they were flies related to the extant family Nymphomyiidae,[2] and two of the species (and genera) in the group were determined to be synonyms.[2] The original hypothesis was that the insects were wingless and were probably ectoparasites of pterosaurs,[1] mostly due to their enlarged hind legs, which were theorised as useful for grasping hair and feathers;[3] however, additional fossils showed that both sexes had deciduous wings, and that only males had enlarged hind legs, used to grasp the females during mating.[2] The family is now known from two species in the genus Strashila and one in the genus Vosila.[2]
