Identification

Adult Markings: This is a distinctively marked Acleris with resting individuals having a silvery-gray, donut-shaped pattern that encloses a horse-shoe-shaped chestnut-brown mark. The palps, head and antennae are silvery-gray and the thorax mostly so except for a thin, faint, chestnut-brown, weakly curve line on the anterior end, and a chestnut-brown spot or short, longitudinal dash on the posterior margin. The forewing has a conspicuous, broad, silvery-gray arc that extends from the wing base and gradually narrows before terminating at or near the inner margin at around one-half the wing length. The region inward from the silvery-gray arc consists of a smaller dark-brown arc along the inner margin, with the proximal end often being continuous with similar-colored marks on the posterior half of the thorax. The area distal to the silvery-gray arc has a chestnut-brown ground colored that is overlain with varying amounts of silvery-gray frosting. The entire wing often has varying degrees of fine, widely-spaced, dark brown speckling, with the specks often evident along the outer margin of the silvery-gray arc. The fringe is silvery-gray and the hindwing varies from tan to light-brown.

In North Carolina, A. maculidorsana is most easily confused A. robinsoniana. In A. maculidorsana, the curved line on the anterior edge of the thorax is chestnut-brown, the outer edge of the silvery-gray arc is relatively smooth, the posterior half of the wing is usually overlain with silvery-gray frosting, and the forewing is speckled with fine dark-brown marks. In A. robinsoniana, the line on the anterior edge of the thorax is dark-brown to blackish-brown, the outer edge of the silvery-gray arc is relatively wavy, the posterior half of the wing has little or no silvery-gray frosting, and the forewing has less speckling. In addition, the dark mark along the inner margin on the basal fourth of the wing tends to be arc-shaped in A. maculidorsana versus more triangular-shaped in A. robinsoniana.
Wingspan: 17-20 mm (Forbes, 1923).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
