The cheese fly (Piophila casei) is a species of fly whose larvae are known for infesting human foodstuffs including cured meats, smoked or salted fish, cheeses and also carrion. The larvae of this fly are known as cheese skippers, bacon skippers, ham skippers, etc. due to their ability to launch themselves several inches into the air when alarmed or disturbed. In the Mediterranean island of Sardinia, the larvae are intentionally introduced into pecorino cheese to produce the characteristic casu marzu ("rotten cheese" in Sardinian). When consumed, the larvae can survive in the intestine, causing enteric myiasis.[1]
