White-spotted prominent moth

Woodlands, forest edges, parks, and gardens across eastern and central North America, especially where host trees and shrubs grow.

Caterpillars feed mainly on foliage of plants such as basswood, elm, maple, oak, and related trees; adults generally do not feed or take little nectar.

Nocturnal and attracted to lights; adults rest with patterned forewings covering the hindwings. Caterpillars are solitary leaf-feeders and pupate in loose soil or leaf litter, often overwintering as pupae.

Harmless to people and not medically significant. Larvae contribute to food webs and natural leaf herbivory, though locally abundant caterpillars may cause minor ornamental-plant damage.
