Habitats and Life History
Habitats: Habitats include barrens, woodlands, and forests (Wagner, 2005). Our records come from upland habitats, including hardwood forests and woodlands, Spruce-Fir forests, and heathlands.
Larval Host Plants: Polyphagaous, larvae feed on a wide range of families of hardwood trees and shrubs. Wagner et al. (2001) specifically list maple (Acer), alder (Alnus), birch (Betula), Pecan (Carya illinoinensis), New Jersey Tea (Ceanothus americanus), hackberry (Celtis), Eastern Redbud (Cercis canadensis), walnut (Juglans), larch (Larix), apple (Malus), oak (Quercus), poplar (Populus), cherry (Prunus), gooseberry (Ribes), Black Locust (Robinia pseudoacacia), rose (Rosa), willow (Salix), mountain-ash (Sorbus), elm (Ulmus), and blueberry (Vaccinium). In North Carolina, larvae have been observed feeding on Black Locust (Robinia pseudoacacia) and maple. - View
