It is single brooded and generally appears in March in
Himachal Pradesh. "The female lays her eggs on the young leaves of
Machilus odorattisimus trees, Natural Order Lauraceae, about the end of April. The larva is at first of a reddish colour but very soon turns black and white, and lies on the upper surface of a leaf where it greatly and protectively resembles a bird's droppings." Adult larva: brown with two subdorsal and two lateral rows of fleshy-pointed tubercles, each with a spot of red at its base; anterior, middle and posterior lateral patches of dull ochraceous, the latter two meeting on the dorsum; the rest of the larva spotted with black and red." Pupa dark brown with lines of dull ochraceous, roughened, with the anal end truncate." (Described from plate to Mackinnon & de Niceville's paper.) ==Subspecies==
