It has excellent camouflage when at rest as it folds its wings close to its body, lays back its antennae, and mimics a broken stem or twig. A dark leading edge and a dark kidney mark on the forewing readily distinguishes this species from others that maybe similar.Wingspan 27 to 32mm. Forewing length 14 to 16mm.
