Egg: The egg of the bot fly is creamy colored and oval in shape, and is attached to different species of blood-feeding insects captured by the female bot fly. The eggs, usually attached to the ventral side of the body, hatch when the insect carrying the eggs begins to blood feed on a warm-blooded host.

Bot Parasite Infestation in Horses. Botflies are an unfortunate byproduct of caring for horses. They are a frequent source of irritation for horses, especially during the hot months of late summer, when these flies seem to be always around. The larvae of the botfly is referred to as a bot, and a horse that is infested with botfly larvae is said to have bots.

Adult: The adult bot fly is 12 to 18 mm long with a wide array of colors (Kahn 1999, Sampson et al. 2001). The face is yellow with a metallic blue abdomen and orange legs and each body segment is covered with hairs which give the fly a bumblebee appearance (Khan 1999).

Life Cycle. There are three species of horse bots. Their life cycles are very similar, except in where they attach their yellow to gray eggs to the host. Common horse bot eggs most often are attached to hairs on the fore legs but can be found on the outside of the legs, the mane and on the flanks.

The human bot fly is native to Central and South America. The fly is not known to transmit disease-causing pathogens, but the larvae of D. hominis will infest the skin of mammals and live out the larval stage in the subcutaneous layer, causing painful pustules that secrete fluids.

While bot flies may or may not be noticed around horses, it is easy to look for nits, or eggs, on the animal's coat. Virtually all horses in Kentucky are likely to be infested. Most of the pest life cycle occurs in the horse. Consequently, an insecticide, applied internally, is necessary to provide effective control.

Bot Flies, aka Torsalo or Dermatobia hominis. Bot flies (Order Diptera, Family Cuterebridae) are large, stout bodied, hairy flies that resemble bumblebees. The botfly egg is deposited by a mosquito or sometimes by another insect. The larva grows in the host's body until it is fairly large.
