The Warble Fly is a type of fly belonging to the family Oestridae. These flies are known for their role as parasites, particularly affecting livestock such as cattle and sheep. The female Warble Fly lays its eggs on the host animal's skin, and the larvae burrow into the flesh, causing discomfort and potential health issues. Warble Flies are most commonly found in temperate regions and are particularly active during warmer months. Their life cycle includes several stages, from egg to larva to adult fly. Control measures often involve veterinary treatments to manage infestations and protect livestock health.
