This Caterpillar is grey, with a dark dorsal line, and dark marks enclosing a red or orange spot on the shoulders of each segment. It is covered in sparse long white hairs, which can cause urticaria. The thorax and head are brown, and the first and last abdominal segments are dark. When young, the caterpillars are gregarious. They feed on the older leaves of :

  • various species of Gum Trees ( Eucalyptus, MYRTACEAE ).
