bird flies, filth flies
Carnidae is a family of small flies (Diptera) comprising six genera and approximately 93 species worldwide. Most species are saprophagous, with larvae developing in bird nest litter, dung, carrion, and decaying organic matter. Members of the genus Carnus are exceptional within the family, being haematophagous ectoparasites of nestling birds. Adults are typically 1–2 mm, black, and characterized by distinctive arrangements of orbital setae on the frons.
