Seasonal development and life cycle—Peachtree borer

Adult peachtree borers emerge in the late spring or early summer. Female moths lay their eggs during the summer on bark at the base of tree trunks. Hatching larvae tunnel into the tree at or slightly below ground level. The larvae feed in the crown area and burrow up into the tree, leaving piles of frass at their burrow entrances. In the late spring they pupate near the entrance of their burrows or in the soil. Adult moths emerge 20 or 30 days later. The peachtree borer has only one generation a year.
