The Sigmoid Prominent is a small, beautifully patterned prominent moth with brown-and-white wings bearing a distinctive S-shaped dark marking — the sigmoid that gives it its name. It is associated with poplars and aspens. Adults rest with the body arched and wings raised at the front, the characteristic 'prominent' posture.
