Lycomorpha pholus
black-and-yellow lichen moth
Lycomorpha pholus, the black-and-yellow lichen moth, is a diurnal moth in the family Erebidae. It occurs across much of eastern and central North America, where adults are active from late summer through fall. The species participates in a Müllerian mimicry complex with net-winged beetles (family Lycidae), sharing their distinctive black-and-orange warning coloration. Larvae feed on lichens and are cryptically colored to match their substrate.
