Cephenemyia jellisoni
nose bot fly
A parasitic bot fly whose larvae develop in the nasal passages and pharyngeal recesses of deer. Adults are active during warm periods and exhibit specific mating aggregations on elevated vegetation. The species shows a covert attacking strategy when larvipositing, remaining undetected by hosts until the moment of larval deposition.
Cephenemyia pratti
nose bot fly
Cephenemyia pratti is a species of nose bot fly in the family Oestridae, described by Hunter in 1916. Like other members of the genus Cephenemyia, it is an obligate parasite of cervids (deer family). The species is poorly documented in scientific literature, with only six observations recorded on iNaturalist as of the knowledge cutoff.
Oestrinae
Nose Bot Flies
Oestrinae is a subfamily of bot flies (Oestridae) comprising 9 genera and 34 species of obligate mammalian parasites. Larvae develop within the nasal, pharyngeal, and frontal cavities of deer, sheep, and related ungulates, feeding on cellular debris and mucosal secretions. Adult females are larviparous, depositing live larvae directly into host nostrils. The subfamily includes economically significant pests of livestock and game animals.
Oestrus
bot flies, sheep bot flies
Oestrus is a genus of bot flies in the family Oestridae, parasitic on mammals. The best-known species, Oestrus ovis, commonly called the sheep bot fly, deposits larvae in the nasal cavities of sheep and goats, where they develop and cause respiratory distress. Adults are non-feeding and have reduced mouthparts. The genus has a Holarctic distribution, with records from northern Europe and other temperate regions.
