Piophila casei (English spelling)

...The larvae feed on rotting plants. The cheese fly family is small, with a body length of less than 5 mm. The representative species, the cheese fly Piophila casei , is distributed throughout the world, and is particularly well-known in Europe for its larvae that appear in high-protein stored foods such as cheese, bacon, and dried meat. The larvae have the habit of curling up their bodies and then suddenly stretching them out, which causes them to jump up in recoil, hence the name cheese skipper.
