( Latin: Piophila casei)
This fly lays its eggs not only on cheese but also on other milk products, on meat as well as offal and faeces. The larvae, known as cheese skippers, have a fantastic ability to hop. They do this by bending themselves in the middle so that they can grasp the hind part of the body with the mouth- hooks. They then suddenly release their hold and the body is hurled into the air. At one time they were something of a scourge in shops selling cheese and smoked products and also in private houses, but they have now become very rare pests.
