Cephenemyia phobifer
pharyngeal bot of white-tailed deer
Cephenemyia phobifer is a parasitic bot fly (family Oestridae) that develops in the pharyngeal region of white-tailed deer (Odocoileus virginianus). The species exhibits probable larviposition, with females depositing live larvae directly onto or near hosts rather than laying eggs. It has a northeastern Nearctic distribution and completes two generations annually, with winter and summer cycles differing in duration.
