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 larvae 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. 



The Angoumois Grain-moth (Sitotroga cerealella Oliv.) 



In the Southern states stored grain is severely attacked by a very 

 small grub which starts work within the kernels in the field, and con- 

 tinues its depredations after the grain is harvested and stored. The
