Oestridae

 Sheep bot fly Oestrus ovis, photographed by terraincognita96.

Belongs within: Oestroidea.
Contains: Gasterophilinae.

The Oestridae, bot flies, are large flies whose larvae are parasitic on mammals. Larvae of Cuterebrinae and Hypodermatinae occupy a subdermal position in their host whereas Oestrinae infest the naso-pharyngeal area and Gasterophilinae are intestinal. The Cuterebrinae are found only in the New World and are parasites of rodents and lagomorphs, with the exception of the African elephant parasites Ruttenia loxodontis and Neocuterebra squamosa whose affinities are uncertain. The Oestrinae mostly attack artiodactyls with some species parasitising equids, elephants and kangaroos. The Hypodermatinae include parasites of artiodactyls, rodents and lagomorphs (Wood 1987). Adult bot flies have reduced mouthparts and largely do not feed, though some are known to imbibe fluids by pressing the underside of the head to a damp substrate (Wood 1987).

Characters (from Pape 2010): Large, robust flies (body length 15-25 mm) with reduced mouthparts and body clothed with pilelike setosity. Body colour blackish, yellowish or metallic blue. Antenna usually short. Arista bare, pectinate or plumose. Vein M either almost straight or weakly to strongly bent, vein R1 without knob at level where subcosta joins costa. Legs short and stout, or slender. Abdomen globose or elongate oval. Male terminalia with small and simple sternite 5, cerci and surstyli relatively unmodified or shortened, phallus short and stout, with or without epiphallus.
