Family Oestridae is a group of flies commonly known as bot flies or botflies. These flies are known for their unique life cycle, which involves larvae parasitizing various warm-blooded animals, including humans, causing myiasis, a disease that can be fatal in some cases. There are many synonyms for the family Oestridae, including warble flies, heel flies, and bot flies. In North America, they are commonly referred to as deer flies due to their tendency to infest deer. In South America, they are known as torsalo or berne. Despite their various names, these flies are a serious threat to the health of both humans and animals, making their control and prevention a priority.
