The single fine species, Carthaea saturnioides from south-western Australia (Common 1966b), is grey with a rose-flushed hind wing. When disturbed suddenly, the insect displays its eye-spots by depressing the head, protracting the fore wings, and moving the hind wings rhythmically. The handsome, orange and brown larva, with lateral eye-spots, feeds exposed in the early summer on the young foliage of Dryandra , Banksia and Grevillea (Proteaceae).
