Oestridae (Botflies)

The botflies, also known as warble flies, heel flies and gadflies, are a family of flies technically known as Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. The human botfly, Dermatobia hominis, is the only species of botfly known to parasitize humans routinely, though other species of flies do cause myiasis in humans.
