The Piophilidae are a family of "true flies", in the order Diptera. The so-called cheese flies are the best-known members, but most species of the Piophilidae are scavengers in animal products, carrion, and fungi. They may accordingly be important in forensic entomology and medical entomology. For a fly maggot, the larvae of many species have an unusually well-developed ability to leap when alarmed or when abandoning their larval food to pupate; they accordingly may be known as cheese skippers or other kinds of skippers according to their food source.
The most notorious member of the family is the cheese fly, Piophila casei; it is cosmopolitan, and a typical member of the family. It is a small species, about 4 mm (0.16 in) long. The fly's larvae infest cured meats, smoked or salted fish, cheeses, and carrion. The mature larva is about 8 mm (0.31 in) long and is sometimes called the cheese skipper because of its leaping ability - when disturbed, this tiny maggot can hop some 15 cm (6 in) into the air. Adults are also known as bacon flies and their larvae as bacon skippers, ham skippers, cheese maggots, cheese hoppers, etc. In the Mediterranean island of Sardinia, the larvae are intentionally introduced into pecorino cheese to produce the characteristic casu marzu ("rotten cheese" in Sardinian).
The adult cheese fly's body is black, blue-black, or bronze, with some yellow on the head, antennae, and legs. The wings are faintly iridescent and lie flat upon the fly's abdomen when at rest. At 4 mm (0.16 in) long, the fly is one-third to one-half as long as the common housefly.
