This Caterpillar is small and green with a pale brown head capsule. It grows to a length of about 2 cms. It has been found in December in Melbourne feeding on :

  • Silver Wattle ( Acacia dealbata, MIMOSACEAE ), and
  • Cootamundra Wattle ( Acacia baileyana, MIMOSACEAE ).

    It conceals itself by making a protective cluster of silk-bowed wattle fronds. If disturbed, it will flee by wriggling backwards.

    The pupa is formed between leaves joined by silk. Initially it is bright green, but it turns brown after a day or so. In summer, the pupal duration is only about a week.

    The adults have forewings that are brown with various black dots, and paler bands along the margin and at the base. The hind wings are brown with a cream edge along the costa. The moths have a resting shape like the outline of a bell. They have a wingspan of about 2 cms.

  • Queensland,
  • New South Wales,
  • Australian Capital Territory,
  • Victoria,
  • Tasmania, and
  • South Australia.
