The adult moth is predominently brown in colour, with bunched hairs on its head which look like a short pair of horns. On each fore wing is a silvery figure of eight, with the segments fused together, unlike its kindred species: Chrysodeixis eriosoma, in which the parts are separated. The hind wings are fawn in colour with a dark brown terminal area. The moths have a wingspan of about 3 cms.

The species occurs over the south Pacific, and through the northern half of Australia. The specimen shown was taken in Sydney.
