The Cheese Skipper (Piophila casei) 
The softer kinds of cheese and the fatty parts of hams or bacon are 
the favorite breeding places of minute, slender maggots that have a 
way of curling the body and then suddenly straightening it, so that 
they throw themselves some little distance. They are the larve of 
very small, grayish flies. 
Infested materials should be removed, and shelving or bins given a 
thorough cleaning, for the maggots will develop in very small quantities 
of grease or other suitable material. It is sometimes necessary to 
fumigate, in order to kill the adult flies that are in hiding.
