Philornis is a genus of around 50 species of fly (Diptera, Muscidae) from Central and South America.

One species, P. downsi, has been accidentally introduced to the Galapagos Archipelago, posing a major threat to some of its endemic birds.

The most extreme intensity was 63 larvae per chick,[4] which is higher than those found for other Neotropical parrots.

[8] The study also described a new and efficient technique to remove larvae using a reverse syringe design snake bite extractor.
