A fascinating account of the speed of a Deer Bot fly, Cephanomvia pratti, was made by entomologist C. H. T. Townsend in 1926 by estimating the speed of the fly as it flew between mountaintops. The fly is best known for its larval stage or maggot. Where bot flies are numerous, they can be serious pests of livestock. Their life cycles vary greatly according to species, but the larvae of all species are internal parasites of mammals. View gallery. It is one of relatively few flies that give birth to live young instead of laying eggs (technically, eggs are produced but hatch within the adult females reproductive tract). The larvae originate from the deer's sinus cavity, nasal passages and/or pouches in the throat region. A smallish family with about 40 North American representatives, the bot flies (family Oestridae) all have larvae that mature as endoparasites on mammals that is, the fly larvae matures inside a mammals body.

The eggs hatch into larvae, which extend a breathing tube up through the skin to exchange oxygen and carbon dioxide. The speed attainable by insects is currently poorly understood and insect airspeed is one of the least known features of flight performance. The Oestridae, in turn, are a family within the superfamily Oestroidea, together with the families Calliphoridae, Mesembrinellidae, Mystacinobiidae, Polleniidae, Rhiniidae, Rhinophoridae, Sarcophagidae, Tachinidae, and Ulurumyiidae.
