[7] [8] Other common names include tabanids, gadflies, green-headed flies, and green flies. [7] The word "Tabanus" was first recorded by Pliny the Younger and has survived as the generic name. In general ...
The best time to deworm horses against Gasterophilus intestinalis is after the first hard frost. This hard frost will kill the females so no new eggs can be laid on the horse that can be ingested. Meaning that the dewormer is acting on the larva attached to the stomach and will also decrease the amount of larva shed in the feces in the spring. [10]
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.
Adult horse flies can be found in July and August. Males of this species feed on plant juices, while female are bloodsuckers. The females have a high fecundity. They can lay about 500 eggs at an oviposition. The larvae pass through 10–13 instars and the full life-cycle lasts 3–5 years. This horsefly may cause appreciable damages on stock farms.

The horse licks at the irritated skin and the larvae transfer to the mouth of horse. The larvae penetrate tissues in the oral cavity, feed parasitically whilst migrating through tissue of the esophagus to finally reach the stomach. The final larval stage is completed with the larvae attached to the mucosa of the horse's stomach.
