The caterpillars of this species are variegated slender loopers, with the front two pairs of forelegs reduced. The caterpillars have two dark spots on the back of the joint between the first and second abdominal segments. The caterpillars have been found feeding on

  • Paperbarks ( Melaleuca species, MYRACEAE ).

    The caterpillars pupate in cocoon spun between joined leaves of the foodplant.

    The adult moths are basically dark orange. There is a pale mark at the tornus and a dark mark at the apex of each forewing. An oval shape near the middle of each wing, is black in the females and pale in the males. The hindwings are a paler orange colour, the male having a dark brown submarginal arc. The wingspan is about 6 cms.

    The adult moths are a pest on fruit, piercing the skin to suck juice.
