This subdued beauty is on the wing from mid-May to mid-July in moist forest habitats. Their wings can do a unique trick (along with other species in the tribe Phlogophorini). The wings pleat when the moth is resting with wings folded back. Larvae are very broad generalists, feeding on all types of herbaceous vegetation, ferns, hardwood shrubs and trees, and on conifers. American angle shades are widely distributed and can be found throughout much of North America.
