Horse botflies are large, hairy insects belonging to the family Gasterophilidae. They are known for their distinctive appearance, with a robust body and large, prominent eyes. These flies lay their eggs on the legs and bodies of horses, and when the larvae hatch, they enter the horse's digestive system, where they can cause discomfort and health issues. The life cycle of horse botflies includes several stages, starting from the egg to the larval stage and finally to the adult fly. Horses are the primary hosts for these flies, and their presence can lead to problems such as colic and weight loss. Effective management includes regular grooming and veterinary care to minimize infestations.
