and life cycle—Branch and twig borers
Adult branch and twig borers are present from early spring through early summer. Males are frequently
found attending females while they feed. Eggs are laid singly in protected areas. Larvae emerge in May
or June and bore into dead wood where they continue to feed. The larva remains in its burrow for 10 months.
It then prepares a hollow cell in which to pupate. Adults emerge from pupae within 2 weeks of pupation.
