This Caterpillar is initially green with a dark brown dorsal line. In later instars, the dorsal line breaks into a series of dark patches, one on each segment.

In the last instars, the dorsal line only extends along the thorax, and a becomes a series of brown spots on the abdomenal segments, The spiracles are white with red outlines. It feeds on the foliage of plants in MYRTACEAE such as

  • Gum Trees ( Eucalyptus species ), and
  • Geraldton Wax ( Chamelaucium uncinatum ),

    as well as other plants including

  • Golden Wattle ( Acacia pycnantha, MIMOSACEAE ), and
  • Peruvian Pepper ( Schinus molle, ANACARDIACEAE ).

    Later, the caterpillar becomes reddish, especially the head and tail, but retaining the same markings.

    The adult moth of this species has pale grey patterned forewings with dark veins. The hindwings are plain white. The wingspan of the males is about 5 cms. The wingspan of the females is about 6 cms.

    Unusually for Geometrids, it folds its wings tightly along its back when at rest, making a shape that tapers to a point at the end of the abdomen.
