A botfly, [1] also written bot fly, [2] bott fly [3] or bot-fly [4] in various combinations, is any fly in the family Oestridae. Their life cycles vary greatly according to species, but the larvae of all species are internal parasites of mammals. Largely according to species, they also are known variously as warble flies, heel flies, and gadflies.
Either the eggs hatch while the mosquito is feeding and the larvae use the mosquito bite area as the entry point, or the eggs simply drop off the muscoid fly when it lands on the skin. The larvae develop inside the subcutaneous layers, and after about eight weeks, they drop out to pupate for at least a week, typically in the soil.
The third stage: The larvae are mature enough to develop their pupa, and once finished they are released with the animal feces during spring. After leaving, which occurs in about 3-10 weeks,(depending on the temperature) [5] the adult bot fly emerges from the pupa and starts the cycle again.
Immature and mature larvae of the sheep bot fly. Sheep bot flies commence life as eggs within the female which are fertilised and hatch to larvae of 1 mm within the body of the female. The female then deposits a few larvae, while on the wing, within a tiny mucous drop, directly into a nostril of the host animal.
The fly would have produced an audible sonic boom; The supersonic fly would have been invisible to the naked eye; and; The impact trauma of such a fly colliding with a human body would resemble that of a gunshot wound. Using the original report as a basis, Langmuir estimated the deer botfly's true speed at a more plausible 25 mph (40 km/h).

Gasterophilus nasalis (also called throat bot fly or horse nasal bot fly [2]) is a species of the genus Gasterophilus and family Oestridae. This species is found worldwide, but prominently present within the summer months. This species of G. nasalis primarily targets equines, such as horses, donkeys and the plains zebra. [3]
