These Caterpillars may be any colour from green to brown with white patches along the sides. They have flaps along the back that resemble leaflets of their foodplant. They move in looper fashion as they are missing the first three pairs of prolegs.

The caterpillars have been found feeding on the flowers and young foliage of various plants, including :

  • Pithecellobium species ( MIMOSACEAE ),
  • Black Wattle ( Acacia leiocalyx, MIMOSACEAE ),
  • Bark Wattle ( Acacia decurrens, MIMOSACEAE ),
  • Curracabah ( Acacia concurrens, MIMOSACEAE ),
  • Hickory Wattle ( Acacia aulacocarpa, MIMOSACEAE ), and
  • Roses ( Rosa species, ROSACEAE )
