The caterpillars have been found feeding on

  • Sticky Hopbush ( Dodonaea viscosa, SAPINDACEAE ),

    but have been reared more successfully on

  • Golden Wattle ( Acacia pycnantha, MIMOSACEAE ).

    The adult moths of this species are brown with a variable spotty pattern of dark markings including a vague submarginal band, and a very dark line along the inner margin of each forewing. The hindwings are off-white shading to grey at the margins. The wingspan is about 3.5 cms.
