This Caterpillar is greyish-green with raised white spots. It has rows of long white hairs along its body. It feeds on :

  • Bland Mistletoe ( Notothixos leiophyllus, SANTALACEAE ).

    Young instars are gregarious, but later instars are solitary. The caterpillars spread silk around the leaves where they are feeding.

    The pupa is formed often some metres from the foodplant. It is yellow and has a forked head. Its length is about 2.5 cms.
