Initially this Caterpillar emerges from a cluster of white eggs, which usually have been laid on a leaf of a foodplant. The caterpillar is initially white with a black head.
Later instars have a brown head capsule, and are very hairy, with black or dark brown hairs covering the thorax and abdomen.
In later instars the hairs on the first few abdominal segments become paler and rust coloured. In direct light with a darker background the hairs can appear pale yellow, and the body can be seen to be brown with rows of pale yellow spots on the back and sides.
The hairs cause a slight rash in some people.
The caterpillar feeds on a variety of herbaceous plants from a variety of families, including:
and in South Australia, it is a pest on plantations of:
The caterpillars feed happily thoughout daylight hours. The later instars are a lawn-keepers friend, consuming two whole Dandelion leaves each day. The caterpillars grow to a length of 5 cms.
The caterpillars pupate in a loose cocoon incorporating larval hairs and local detritus, under a log or bark or in a crevice. The pupa inside is a shiny very dark brown, with a length of about 2 cms.
The adult moths are very attractive, with a wingspan up to 6 cm, although the female is slightly larger than the male. The wing pattern is variable, but is commonly white with extensive black or dark brown markings.
The abdomen is ringed in black and scarlet. Under the white hairs, the thorax is black, unlike that of the similar species Spilosoma canescens, which has a white thorax.
The species may be found over the whole of the southern half of Australia, including
