No. 39. THE ORANGE FLY. 



This is one of the best flies that can be used, 

 especially for Grayling. There are a great 

 many species ; some larger, some smaller, than 

 the representation. It may be used all day. 

 Although discovered alive with difficulty, it is 

 found abundant in the stomachs of the fish. 

 It is furnished with apparatus called the sting, 

 or ovipositor, used for the purpose of piercing the 

 skin of caterpillars, in which it deposits its eggs, 

 the grub from which grows in, and ultimately 

 kills, the insect in which it was hatched. These 

 Ichneumon flies are the great check to the mul- 

 tiplication of the insect tribes.
