The Dimorphic Macalla moth has a wingspan of approximately .75 inch. The straw-colored forewing (sometimes greenish) has contrasting chocolate brown shading beyond the angled postmedian line. The hind wing is mostly plain gray except for some brown markings in the terminal area. The caterpillar is yellow and black striped. The head is black with a large white spot in the clypeus.
The frequency of occurrence in this area is not known, but it is considered to be common in its range which is most of eastern North America. Two individuals were photographed at Neale Woods on 10 June 2016 coming to moth lights. Adults fly late May to August.
Another common name is Dimorphic Epipaschia. The larval food plant is Poison Ivy Toxicodendron radicans. Dimorphic Macalla is the only species in the genus found in North America.
