Forewing whitish, with a very slight tinge of brown, at least in the central area; a narrow subbasal dark band, closely followed by conspicuous broader one, the pale line which separates them angulated anteriorly; the lines of the median area ill-defined, dentate. Hindwing white, nearly always with a narrow greyer distal border and sometimes with one or two indistinct lines in outer half. Forewing beneath very weakly but more uniformly marked; hindwing with very distinct discal dot. Variable in the intensity of the markings. The caterpillar is green, darker below and between the rings.The body is wrinkled, and with two points on the last ring. The most distinct markings are two yellow lines along the back. The head is notched. The pupa is reddish brown. The cremaster has the shape of a small anchor.
