The Caterpillars of this species vary in colour from pink to green, but have a green head and pale stripes along the body. The caterpillars have been found feeding on plants in PRIMULACEAE, including:

  • Coralberry ( Ardisia species ), and
  • Viranga ( Embelia species),

    the early instars prefering to eat younger leaves.

    The caterpillars pupate in a sparse cocoon in a curled leaf of the foodplant.

    The adult moths are pale brown with a number of dark spots. The moths have a wingspan of about 2 cms.

    The eggs are laid singly on the leaves and twigs of a foodplant.

    The species occurs as several subspecies in the oriental tropics, including :

  • Borneo,
  • Malaysia,
  • Sri Lanka,
  • Taiwan,

    as well as in Australia, having been caught in

  • Queensland,
  • New South Wales,
  • Victoria, and
  • South Australia.
