The caterpillars of this species are greenish-grey with vague transverse band and longitudinal stripes. They feed nocturnally on the leaves of

  • Showy Sauropus ( Sauropus albiflorus, PHYLLANTHACEAE ).

    By day, the caterpillars lie along a stem, and are difficult to see. They grow to a length of about 3.5 cms.

    They pupate in a cocoon covered in debris, near the base of their foodplant.

    The adult moths are dark brown with two parallel white lines across each forewing, and one across each hindwing. The moths have a wingspan of about 4 cms. The moths often settle with the head pointing downwards.


    They are found over the northern half of Australia, including

  • Northern Territory,
  • Queensland,
  • New South Wales, and
  • Victoria.
