Pest description and damage Adult moth is reddish brown, with a wingspread less than 0.5 inch, and irregular light and dark bands on the wings. Larvae are 0.5 inch in length, yellowish to greenish, with black spots and a yellow-brown head. Pupae are yellow to brown with a white silken cocoon. The larvae skeletonize and roll leaves from the sides. Damaged leaves are brown and papery and drop prematurely. Damage varies from inconsequential to serious, so monitoring is an important management tool. Damage is rarely lethal to the tree.
