This Caterpillar is green with a black line along the back. The caterpillar is often covered in a white waxy powder. It rests in a tent-like shelter which it makes out of leaves of its foodplant joimed with silk. It rests head downward, as the opening of the shelter is at the bottom. It typically emerges to feed near dusk. It feeds on :

  • Drummond's Flag ( Patersonia drummondii, IRIDACEAE ).

    The pupa is formed head downward in the shelter.
