It was described by Émile Louis Ragonot in 1887, and is known from southeastern Ontario, Canada, and the eastern United States. There are two to four generations per year. The larvae feed on Carya and Juglans species. Larvae of the first generation bore into the new growth of their host plant. The species overwinters in the larval stage.
