Autumn leaf or living insect? These delicate looking moths are typically found flying from mid to late summer into early fall when their dried leaf-like appearance is most helpful for camouflage. They range in size from a 1.7-inch wingspan to a nearly 2.4-inch wingspan — the larger individuals being females. They inhabit mixed and deciduous forests from coast to coast in southern Canada and the northern U.S. (also found south along the east and west coast, being absent in parts of the central and southern states). The larvae are no camouflage slouches themselves, expertly mimicking a twig.
