The Cherry-tree Tortrix 



Ar chips cerasivorana Fitch 



In June and July the 

 ends of the branches of 

 both the wild and culti- 

 vated cherry are often seen 

 inclosed in large, pointed 

 silken nests (Fig. 264). 

 Within each nest there 

 lives a colony of lemon- 

 yellow larvae, about f inch 

 in length when full-grown, 

 all the offspring of a single 

 ochre-yellow moth. As the 

 larvae increase in size the jtig. 265. 

 nest becomes filled with 

 large, dark-colored masses of excrement webbed together with 

 silk (Fig. 265). The larvae mature early in July and pupate 



inside the nest. 

 When about to 

 transform, in the 

 latter ])art of July 

 in New York, the 

 pupae work their 

 way out of the nest, 

 clinging to it only
