Description: Since the initial importation of the Japanese Laricobius (Coleoptera: Derodontidae) to Virginia in 2006, we have studied the development of the predator at two different temperatures, measured feeding and oviposition rates, conducted preliminary host-range testing, and reared two generations. During this time, we have learned this predator differs from Laricobius nigrinus (Fender) in biology and life cycle. Host range tests have been relatively inconclusive, and laboratory survival has been low. These results prompted further investigation of this Laricobius beetle and hemlock woolly adelgid in Japan.
