Wohlfahrtia magnifica, the spotted flesh fly, or sometimes called the screwworm fly, though species of flies from other families go by this name. It is a species of fly belonging to the family Sarcophagidae . The adults are about 6–10 mm in length; third-instar larvae are 5-7 mm in length.
W. magnifica larvae cause myiasis in mammals, mainly in sheep, but also in cattle, goats, horses, and rarely in humans. In sheep, larvae chiefly infest genitalia or open wounds. In humans, W. magnifica larvae may infest the ear, eye, mouth, or nose, damaging living tissues; they may also infest open wounds, including after surgery.
The larvae of the North American species, W. vigil and W. opaca, are incapable of penetrating adult skin; infestation occurs only in infants.
