This, like most Spilosoma Caterpillars, is dark and hairy. The hairs are uniformly brown over the whole body. It has a yellow line down the back, and a brown head.
It eats various herbaceous plants. We have found it feeding on:
It grows to a length of about 3 cm., then leaves the foodplant, and looks for a dry spot in the soil surface debris, where it forms its cocoon and pupates
The moth has white wings with brown flecks. The markings on the wings is interesting, because the pattern and degree of marking differs even between animals reared from the same brood of eggs.

The eggs are white and laid in a patch on a leaf.
The species is found over much of Australia, including:
