The Oblique-banded Leaf-roller 

 Ar chips rosaceana Harris 



The caterpillar of this leaf -roller varies from a light yellowish - 

 brown to apple green in color and is about f of an inch in length, 

 with a brownish-black head and thoracic shield, the latter usually 

 with a whitish cephalic border, and often more or less green 

 bordered with black. It lives in a nest similar to that of the 

 bud-moth, formed by rolling or folding and tying together leaves 

 of apple, pear, cherry, plum, peach, rose, raspberry, gooseberry, 

 currant, strawberry, and several other trees, wild berries, red 

 clover, more than half a dozen weeds, and eats into growing 

 cotton bolls. The insect is common and widely distributed 

 throughout the northern United States, where it is sometimes 

 quite injurious, especially on apple trees. In addition to eating 

 the leaves and often checking the growth of shoots, the cater- 

 pillars sometimes attack the young fruits, either gnawing olT the 

 skin or eating holes in them. 



There are two broods of the caterpillars annually, the first 

 brood working in May and June and the second in July and 

 August.

 brown pupse, from which emerge in a week or ten days the
