Cheese fly

The cheese fly (Piophila casei) is a species of fly from the family Piophilidae whose larvae are known to infest cured meats, smoked or salted fish, cheeses and also carrion. The larvae of this fly are known as cheese skippers or ham skippers due to their ability to launch themselves several inches into the air when alarmed or disturbed. On the Mediterranean island of Sardinia, the larvae are intentionally introduced into pecorino cheese to produce the characteristic casu marzu. When consumed, the larvae can survive in the intestine causing enteric myiasis.
