Habitats and Life History
Habitats: North Carolina records come from a variety of rich hardwood forest, ranging from mesic, high elevation stands, cove forests, and Amphibolite ridges in the Mountains and alluvial and mafic forests in the Piedmont. Coastal Plain sites may all be associated with planted walnuts.
Larval Host Plants: Larvae feed primarily on Black Walnut (Juglans nigra), but have also been reported from Shagbark Hickory (Carya ovata) (Wagner et al., 2011). As of 2024, we have records for both Black Walnut and an unknown hickory species. J.B. Sullivan also recorded a larva on Sweet Birch (Betula lenta). - View
