Between april and may the larvae from this moth eat exit holes through the bark of stone fruit trees. Unlike peachtree borer, LPTB often attacks parts of the entire tree rather than only the lower trunk. Usually they feed and develop in the inner bark and cambium, and infested sites will ooze gum contaminated with frass and bits of bored wood. Feeding damage may cause bark to peel off in places, exposing the tree to other pests and diseases. Older trees, with more accumulated wounds, scars, and pruning cuts, are generally more likely to be infested than younger trees. Heavy infestations can result in girdled branches and tree death.
