Appearance
The wingspan is about 25 mm for males and about 40 mm for females. The wings are silvery-white, the anterior pair with three small black spots in the middle and a marginal row at the extremity; hinder wings black in the male, white in the female, with a series of angular black marks at the hinder margin: abdomen with a square spot of bright red toward the base.Behavior
The larvae feed on ''Pultenaea villosa'', ''Acmena smithii'', ''Backhousia myrtifolia'', ''Syzygium australis'' and the introduced ''Psidium guava''. The larva bores downwards a cylindrical chamber in the centre of the stem of the host plant. The entrance is arched over with a fabric of web and excrement, under which it feeds during the day. Adults are on wing in November, December, January, February and March.References:
