This Caterpillar is dark grey with yellow mottling. A pair of pale yellow lines run along each side of the back each ending in an enlarged pale spot on the final segment. There are red or white rings between the segments, and a pair of blue spots on the back of each segment. The legs are red, and there are three red or yellow lines on the prothorax. There are three smaller and more widely spaced orange marks on the head. The body and head have sparse thin white spines.

The caterpillars have been reported feeding on a variety of herbaceous plants, including :

  • Pigface ( Carpobrotus rossii, AIZOACEAE ),
  • Capeweed ( Arctotheca calendula, ASTERACEAE ),
  • Early Nancy ( Wurmbea dioica, COLCHICACEAE ),
  • Subterranean Clover ( Trifolium subterraneum, FABACEAE ),
  • Storksbill ( Erodium species, GERANIACEAE ), and
  • Sheep's Sorrel ( Rumex acetosella, POLYGONACEAE ).

    Sometimes, however, they are an agricultural pest on pastures in Australia.

    The caterpillars are great excavators, digging a burrow when mature in which to pupate underground. For caterpillars collected in Narrabri in September, the adults emerged the following May.
