Harris’s three-spot moth (Harrisimemna trisignata) is a small North American moth with a wingspan of about 1¼ inches. Its mottled gray and brown forewings feature distinctive dark spots, giving it its common name. Like many moths, its subtle coloring helps it blend into its surroundings.
Diet: Caterpillars feed on the leaves of a variety of trees and shrubs, including willow, ash, apple, winterberry, and bush honeysuckle. Adults’ feeding habits are not well documented.
Range: Found across much of eastern and central North America, from southern Canada south into the United States, with records extending west to the Great Plains and Arizona.
Habitat: Woodlands, forest edges, and other habitats where suitable host trees and shrubs grow. Adults are most often recorded from spring through fall, depending on location.
Interesting Fact: Despite its small size and understated appearance, Harris’s three-spot moth belongs to a remarkably diverse group of insects whose caterpillars help support woodland food webs. Its caterpillars can feed on many different kinds of woody plants rather than relying on just one host species, giving them flexibility in the habitats where they live.
