    The adult butterfly is dark brown with three or four sets of pale yellow spots on each forewing. Underneath, they are pale brown with a large triangular dark patch under each forewing, and a series of rusty brown spots under each hindwing. The wing span is about 3 cms.

    The females lay their eggs in the dry season on potential foodplants, but the eggs do not appear to hatch until they have been sprayed with water (with the onset of the spring rain, and the consequent regrowth of the grass).

    The species is found in

  • Western Australia.
