The early instars are a translucent pale green with a black spot each side of the second abdominal segment, and a pale brown head. The first pair of prolegs is underdeveloped, so that it moves in a looper fashion.

later instar

Later instars are opaque and fawn with dark speckles, with a pair of small horns on the last abdominal segment. The last instar is uniformly fawn with dark spiracles. The Caterpillar grows to a length of about 4 cms.

last instar

The adult moth is light and dark brown in a pattern that resembles distinctive eye and eyebrow markings on the forewings.

The markings are much less striking in a set specimen. The moth has a wingspan of about 4 cms. We have found specimens in Bundaberg (Queensland), and in Sydney (New South Wales).
