The wingspan is about 30 mm. Adult females are white and have an orange tuft on the tail. Males are also white but sometimes have a dark mark at the tornus of each forewing or a broad dark band along the margin of each forewing. The hairs around the thorax are sometimes yellowish. Sometimes the black skin of the thorax and/or abdomen shows through between the white hairs.

It is considered a pest on Pinus radiata, but has also been recorded feeding on Acacia, Eucalyptus, Pultenaea, Dodonaea, Choretrum, Myoporum and Tamarix. The caterpillars are brown and hairy, with a pencil of black hairs each side of its head and a hairy tail.
