Adults are active from April through September, and are attracted to lights.
Larvae feed on a number of hardwood species, and have an unusual preference for sound rather than rotting wood. Yanega (1996) reports, "The Ivory-marked Beetle is notorious for emerging from furniture and flooring after as many as 10-40 years."
