Zeller's Macalla Moth, Zeller's epipaschia moth
Macalla zelleri is a snout moth in the family Pyralidae, first described by Augustus Radcliffe Grote in 1876. The species is notable for having caterpillars that feed on poison ivy (Toxicodendron radicans), potentially offering a biological control for this problematic plant. Adults are found across eastern and central North America, with records spanning from southern Canada to the southwestern United States.
