The Pink-washed Aristotelia moth has a wingspan of about .50 inch. The forewing has a bold pattern of oblique black and white bands. The 3rd black band is incomplete. The 4th black band curves from the apex to meet the 3rd band. There is pink shading on each side at the inner margin. The hindwing is gray. A similar moth, A. rubidella, has the same patterning but the light bars are relatively dark, never predominantly white. The larva is tan colored with short rows of white lines the length of the body. This moth was identified by volunteer experts at the BugGuide website.
