The Congo floor maggot (Auchmeromyia senegalensis) is a species of blow-fly that is native to sub Saharan Africa and the Cape Verde Islands. A. sengalensis is an atypical myiasis species which does not live on or in the host, but sucks the blood of burrow-dwelling wild pigs, warthogs, aardvark, hyena and occasionally sleeping humans (sanguinivorous myiasis).
Chrysomya bezziana, also known as the Old World screwworm fly or screwworm, is an obligate parasite of mammals. Obligate parasitic flies require a host to complete their development. Named to honor the Italian entomologist Mario Bezzi, this fly is widely distributed in Asia, tropical Africa, India, and Papua New Guinea.
Gasterophilus intestinalis (DeGeer) is the more common horse bot fly which is an internal parasite of the gastrointestinal tract. Gasterophilus nasalis (Linnaeus), the nose bot fly, and G. haemorrhoidalis (Linnaeus), the throat bot fly, are also distributed throughout North America.
Myiasis of the human eye or ophthalmomyiasis can be caused by Hypoderma tarandi, a parasitic botfly of caribou. It is known to lead to uveitis, glaucoma, and retinal detachment. Human ophthalmomyiasis, both external and internal, has been caused by the larvae of the botfly.
Oestrus ovis, the sheep bot fly, is a widespread species of fly of the genus Oestrus. It is known for its parasitic predation and damage to sheep, deer, goats and sometimes cattle. There have also been many records of horse, dog and human infestation. In some areas of the world it is a significant pest which affects the agricultural economy.
