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.
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 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.

About three to seven days after hatching, the larvae fall to the ground to pupate. The pupae reach the adult stage about seven days later. Female screwworm flies mate four to five days after hatching. The entire lifecycle is around 20 days. A female can lay up to 3,000 eggs and fly up to 200 km (120 mi) during her life.
Larvae of Dermatobia hominis, Torsalo bot-fly; third stage larva top, first stage larva bottom. Furuncular myiasis at shoulder and neck of cow caused by infestation of Dermatobia hominis larvae. Typical genera are Hypoderma, Gasterophilus, Dermatobia and Oestrus (fly). Oestrid flies at their larval stage tend to be adapted to feed on a few ...
The female flies lay their eggs on the sheep in damp, protected areas of the body that are soaked with urine and feces, mainly the sheep's breech . It takes approximately eight hours to a day for the eggs to hatch, depending on the conditions. Once hatched, the larvae then lacerate the skin with their mouthparts, causing open sores.
