Habitats and Life History
Habitats: North Carolina records come from maritime and bottomland forests, Longleaf Pine habitats, peatlands, and dry hardwood slopes.
Larval Host Plants: Larvae are apparently polyphagous. Covell (1984) lists cherry (Prunus) as the host plant. Robinson et al. (2010) additionally list oak (Quercus), willow (Salix), poplar (Populus), and birch (Betula). In North Carolina, we have records for it on Yaupon Holly (Ilex vomitoria) and Titi (Cyrilla racemiflora) (J.B. Sullivan, pers. obs.). - View
