The Caterpillar of this species is black with white markings, particularly on the enlarged last segment. and has an orange head. The caterpillar is missing the first two pairs of prolegs, so walks in a looper fashion. The caterpillar has been found feeding on :

  • Snake Vine ( Stephania japonica, MENISPERMACEAE ), and
  • Barbwire Vine ( Smilax australis, SMILACACEAE ).

    The adult moth is brown with a darker diagonal mark across each forewing. The forewings look as though they had a slice cut away from each of the hind margins.

    There is a crest of scales halfway along the hind margin of each forewing that disguises its shape when the moth is at rest with the wings folded. The moths have a wingspan of about 2.5 cms.

    The species occurs over south-east Asia, including

  • Hong Kong,
  • India,
  • Okinawa,
  • Papua New Guinea,

    and in Australia, the species may be found over most of

  • Queensland, and
  • New South Wales.

    The adult moths have been accused of piercing fruit, particularly grapes and peaches, causing losses to orchard owners.
