These Caterpillars have orange and black bands with white patches, and appear to mimic a coral snake, for example Simoselaps australis.

The uppersides of the wings of the adult moth of this species are white with a pattern of yellow and black dots. The undersides are black with grey and white patches near the middle and the base of each wing. The thorax is black, and the abdomen is yellow. The wingspan is about 5 cms. There is no white patch under each forewing tip, which distinguishes it from the related species: Bracca matutindata.

The species occurs in north Queensland.
