About Hypena baltimoralis Guenée, 1854
Adults of Hypena baltimoralis have a wingspan of 26–32 mm (1.0–1.3 in). When resting, they tuck their hindwings behind their forewings, which creates a triangular overall silhouette. Their forewings are grayish-brown; females may have a lighter tint that is usually absent in males. A large dark patch covers most of the outer sections of the forewings, extending to about three-quarters of the total wing length, but does not reach the inner margin of the wing. The inner margins and lower areas of the wings are mottled grayish-brown, with a dark brown or black diagonal line that stretches inward from each corner. This diagonal line is more clearly visible in females. This species is found in the eastern United States, ranging west and south to Wisconsin, Missouri, Florida, and Texas. It is most commonly observed in or near deciduous forests. The larvae of Hypena baltimoralis feed on maple trees, primarily red maple and silver maple.
