FRUIT INSECTS

oblique-banded, light cinnamon-brown 

 colored moths with a wing expanse of about 

 an inch (Fig. 70). The front wings are 

 reticulated with brown and each is crossed 

 by three broad, oblique dark brown bands. 

 The females lay their eggs in flat patches 

 (Fig. 71) on the bark, and the insect hiber- 

 nates in this stage.

A large ichneumon parasite, Glypta simpUcipes, destroys 

 many of the caterpillars of this oblique-banded leaf-roller. 



The Four-banded Leaf-roller 

 Eidia quadrifasciana Fernald 



This smaller, bright yellow caterpillar, about J an inch long, 

 sometimes works on apple trees with and in much the same way 

 as the oblique-banded leaf-roller. It webs a few leaves together 

 and riddles them. The insect is widely distributed over the 

 northern United States, and has done considerable injury in 

 apple orchards in Delaware, working with the preceding species, 

 and has helped to nearly strip trees in Canada. The moths are 

 lemon-yellow, with the front wings reticulated with orange-red 

 and each crossed by two narrow oblique darker bands. They 

 measure across expanded wings about f of an inch, and have 

 been reared late in May and June. 



These two Tortricid leaf-rollers can be controlled by the 

 measures recommended for the fruit-tree leaf-roller on page 64.
