These Caterpillars are cream colored with reddish brown stripes. The last segment has two black arcs. The head is gey with a black 'V' mark. The caterpillars hide by day in a silken shelter near the top of a foodplant, made by joining dead leaves and debris. The caterpillars feed noctunally on species in ASPARAGACEAE, including:

  • Preiss' Thornseed (Acanthocarpus preissii),
  • Thick Thornseed (Acanthocarpus robustus), and
  • Erect Thornseed (Acanthocarpus verticillatus).

    The adults on top are brown with chequered wing edges. The forewings have several pale yellow spots, and the hindwings have one larger spot. Underneath, the forewings are half brown and half yellow, with orange spots. The hindwings underneath are yellow with several white spots each outlined in black. The butterflies have a wingspan of about 3 cms.
