Gasterophilus, commonly known as botfly, is a genus of parasitic fly from the family Oestridae that affects different types of animals, especially horses, but it can also act on cows, sheep, and goats. A case has also been recorded in a human baby.

Here, we take the opportunity to present an updated catalogue of all nine Gasterophilus species, including revised keys for eggs and adults, and updated diagnoses, host data, distributions, and original as well as major secondary literature for each species.

Gasterophilus intestinalis, also known as horse bot fly, is a species of insect of the family Oestridae, [2] and is found worldwide. [3] The adults, which have a bumblebee-like appearance, are prominently active in the summer. [4] G. intestinalis is primarily a parasite of horses, mules and donkeys, [5] rarely of other animals. [6]

Gasterophilosis is caused by a build up of larvae produced by the horse bot fly (Gasterophilus spp.), which is an internal gastrointestinal parasite of horses. Adult bot flies deposit their eggs on the horses’ haircoat, at different locations depending on the species of fly.

Species of Gasterophilus Leach are obligate parasites in domestic and wild equids and responsible for cosmopolitan gasterophilosis. Although with only eight species known so far, they have received considerable attention because of their …

The Gasterophilinae are a subfamily of Oestridae which includes large, parasitic flies; this group has historically been treated as a family, but all recent classifications place them firmly within the Oestridae. [1] . Many members of this subfamily spend part of their larval stages in the digestive tracts of herbivores.

Gasterophilus infection may cause clinical issues including mild gastritis and ulceration. Discussion of incidence, presentation, diagnosis, treatment.

Greek: gaster = stomach, phil = loving it. Adults do not feed, larvae hatch in the case of G. intestinalis within 7–14 days. Human infections may occur after contact with infested horses with G. nasalis, G. intestinalis and G. haemorrhoidalis. The larvae penetrate human skin and migrate in a serpentine causing a line.
