2io THE STUDY OF INSECTS 



It was this habit that suggested the name Tortrix for the typical genus, 

 from which the name of this family is derived. A large portion of the

rolled leaves found upon shrubs and trees 

 are homes of tortricid larvae; but it should 

 be remembered that the leaf-rolling habit is 

 not confined to this family. While many 

 are leaf-rollers probably a larger number are 

 borers in stems, buds, or fruits. 



Several of our better-known members 

 of this family belong to the genus Archips. 

 This is the genus Caccecia of many authors. 

 These insects have been named "the ugly- 

 nest tortricids; ugly dwelling being the meaning of Caccecia, and also 

 descriptive of the nests of the larvae of these insects. The four fol- 

 lowing species are common. 



The oblique-banded leaf-roller, Archips rosacedna. — The larva of 

 this moth feeds within the rolled and webbed-together leaves of apple, 

 pear, cherry, plum, and other fruits. The larva is light yellowish-brown 

 to apple-green in color and about § of an inch in 'length. The moth 

 expands about one inch. It is cinnamon-brown in color and each front 

 wing is crossed by three oblique bands. 



The cherry-tree ugly-nest tortricid, Archips cerasivorana. — This 

 species lives upon the choke-cherry and sometimes upon the cultivated 

 cherry. The larvae, which are yellow, active creatures, fasten together 

 all the leaves and twigs of a branch and feed upon them (Fig. 362), an 

 entire brood occupying a single nest. The larvae change to pupae within 

 the nest; and the pupae, when about to transform, work their way out 

 and hang suspended from the outer portion of the nest. Here they 

 transform, leaving the empty pupa skins projecting from the nest. The
