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.

The caterpillar feeds on the foliage of plants in various families, including

  • Peruvian Pepper ( Schinus molle, ANACARDIACEAE ),
  • Golden Wattle ( Acacia pycnantha, MIMOSACEAE ),
  • Gum Trees ( Eucalyptus species, MYRTACEAE ), and
  • Brown Boronia ( Boronia megastigma, RUTACEAE ).

    In the last instars: the caterpillar can become yellow or reddish, especially the head and tail. 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.

    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.

    The eggs are laid in a close array. Initially they are white with a dark spot, but become darker as hatching approaches. Their shape is roughly spherical with a fine hexagonal pattern embossed on the surface.
