This caterpillar is initially green with a pair of pale lines along the back, a pale brown head, and a pair of pale blunt horns on the tail. The body has a corrugated look.
Later instars develop a pair of rusty-brown lines along the back, and single white-edged rusty-brown line along each side. The caterpillars are missing three pairs of prolegs, so walk in a looper fashion.
When threatened: the caterpillars stand up on their last pairs of legs, and curl their head under the thorax. The caterpillar feeds on a variety of Wattles (MIMOSACEAE) including
The caterpillar pupates after about four weeks in summer in Melbourne. The pupa initially is green with a pale abdomen. Later it turns brown.
