Laricobius nigrinus Fender (Coleoptera: Derodontidae), native to western North America is being evaluated as a potential biological control agent of the hemlock woolly adelgid, Adelges tsugae Annand (Homoptera: Adelgidae) in the eastern United States. Members of the genus Laricobius are known to feed on adelgids. Illustrations and descriptions of various developmental stages of L. nigrinus are displayed as there is limited published information on the morphology and biology of this predator of the hemlock woolly adelgid.
