These Caterpillars are black densely speckled with off-white spots. They have larger white spots between segments, black hairs on the back or each segment, and a longer single white hair projecting diagonally upward each side of each of the segments of the thorax.
The head has a pale face, black pseudo-eyes, and a rusty-red neck. The caterpillars feed nocturnally on various plants from the family MYRTACEAE, including:
Early instars are gregarious, and are precessionary. Later instars are solitary.
The pupa is formed in a white cocoon in a sheltered spot.
The female adult moths have white forewings, each with a large dark patch containing a golden spot near the centre, and usually a vague dark diagonal line.
The male adult moths also have white forewings, each with a dark patch containing a gold spot, and having a more pronounced dark diagonal line. The hindwings are dark brown.
Both sexes have a very hairy head and thorax, and feathery antennae. The abdomen of both sexes has a dorsal gold spot on each segment. The forewings of both sexes have black and gold chequered edges and a submarginal arc of white spots. The hindwings are dark brown, each with a set of yellow spots along the margin. The moths have a wingspan of about 3 cms.
The eggs are laid under an irregular fluffy mass of fawn hairs.
