Wingspan 3.6 cm. Forewing with a white median band and a large yellow-orange apical patch. This species is less common than most other Dysstroma and is limited to wet conifer forests in the Pacific West. Moths fly in midsummer. Caterpillars have been found feeding on foliage of hazelnut (Corylus cornuta).
Similar species: Dysstroma sobria and Dysstroma truncata both lack the orange apical patch on the forewing.
