This widespread moth is found throughout the United States and southern Canada. It feeds as a larva on a great many host plants, getting its common name from its attacks on apples, pears, and stone fruits such as cherry and peach. But it also feeds on other crops such as alfalfa, grapes, blueberries, walnuts, and onions and on many ornamentals such as elm, cedar, birch, lilac, and others, and is a major pest of oaks in many areas. There is a single generation each year with eggs overwintering and hatching in early spring to coincide with bud break on the host plants. Larvae feed on the tender, early leaves, often causing complete defoliation of the trees. Late stage larvae often roll an edge of a leaf and hold it together as a tube using silk, and then pupate within this tube. Adult moths emerge in late spring and may be present through July, although the live only 3 weeks in any region. Females then deposit their eggs in large masses on the branches or trunk and cover them with a cement-like coating.
Control is often with the use of insecticides sprayed over the foliage shortly after bud break and when the first signs of the larval feeding occur.
