A lover of lichens, the American Idia Moth can be found on tree trunks, stone facings, and other areas hosting its flaky forage.
American Idia moths come in light and dark varieties. Light ones may be pale gray or beige near the head and thorax with darker scalloped lines crossing the wings. Dark versions are dark brown, almost black, with white scalloped lines. All individuals have a warm brown or bronze spot near each forewing's edge interferes with the scalloped lines. A white or ivory crescent crowns the larger brown spots. A band of medium brown along the bottom of the wings is broken into segments.
The American Idia is a kind of Litter Moth. It is small and nocturnal. Look for them at night, feeding on lichens attached to tree trunks from spring through autumn. Two or more broods can be produced each year.
