Maple Spanworm Moth

Also known as Notched Wing Moth, Notched-Wing Geometer, Notch-Wing Moth

Maple spanworm moths showcase extraordinary dead-leaf mimicry, sporting bright yellow-orange wings etched with brownish lines and distinctive deeply notched edges that resemble a ragged autumn leaf. Adult moths emerge in late summer and autumn, often resting on tree trunks or lingering around lights at night while holding their wings held in a steep, tent-like angle. Their larvae are classic inchworms that feed on the foliage of maples, birches, and oaks before overwintering in egg clusters tucked into bark crevices.
