This is a striking Caterpillar which is pale yellow with a pattern of black markings on each segment. It has long white hairs scattered sparsely over its otherwise smooth skin. It has an orange head capsule with black markings, a series of lateral red spots by the prolegs, and an orange rump with two black spots. This orange rump may cause predators such as birds to mistake the tail for the head.
The caterpillar usually feeds on the foliage of:
on which it is an agricultural pest. It is also known to feed on:
The caterpillar grows to a length of about 4 cms. When mature, the caterpillar wanders off for several days, then burrows into the soil to pupate. It develops into a pupa with no cocoon.
The length of the pupal stage varies. In Melbourne, specimens pupating in January emerged in February, but specimens pupating in March did not emerge until the following October.
The adult moths are black with a pattern of white markings on the forewings, and a vague white spot near the middle of each hindwing. The moths have a wingspan of about 4 cms.
Underneath, the wings are similar to the upper surfaces, but the body has bands of black and orange hairs.
Its eye system has been investigated by Horridge et al. as this moth is commonly seen flying in the daytime.
Specimens have been caught in:
