This Caterpillar is basically brown and hairy, with coloured markings, including yellow spots on the thorax, and a dorsal row of pale patches along the abdomen. The head has a pair of black hair pencils, like a pair of hairy horns. The caterpillar also has a hairy tail, and a red dorsal gland on each of the two penultimate abdominal segments.
The underside of the caterpillar is green, and it has a yellow line along each side.
The caterpillar is a pest in South Australia on:
On the Lignum: the caterpillar eats the outer bark, stripping the stems.
The caterpillar is also known to feed on:
The caterpillar pupates in a doubly-tapered off-white cocoon on a twig.
The adult female moth is white, and has an orange tuft on the tail.
The male moths are white, sometimes with a dark mark at the tornus of each forewing, sometimes with a grey mark at the wingtip of each forewing, and sometimes with a broad dark band along the margin of each forewing. Sometimes the hairs around the thorax are yellowish. Sometimes the black skin of the thorax and/or abdomen shows through between the white hairs. The antennae appear to be darker than those of the similar Acyphas chionitis. The moths have a wingspan of about 3 cms. It is possible that the one name is being used for more than one species.
The eggs are laid in a cluster almost anywhere. They are covered by the female with brown hairs from her body.
The species occurs across most of Australia, including:
