👉 Metastreptid flies, also known as strongylidae, are a group of tiny, often parasitic flies that feed on blood and other tissues in their hosts. They are found worldwide, but they are most common in tropical regions like Africa, Asia, and South America. Strongylidae larvae primarily feed on the blood of mammals, birds, and reptiles, causing severe inflammation and tissue damage, leading to infections such as swine flu or foot-and-mouth disease.
