Pupation usually occurs in spring at the end of the larval tunnel in the sapwood, eclosion occurs 12–50 days later, and adults will chew out of the tree approximately one week after eclosion. Adults feed on leaf petioles and can chew through bark on small branches to feed on the vascular cambium. Eggs, larvae or as pupae can overwinter within the tree. In their overwintering phase, pupae are inactive and development does not occur. They resume their life cycle when temperatures are above .
