This Caterpillar is initially green with yellow spots.
Later its body becomes yellow, with a partial dark line along the middle of the back, and has white spiracles with dark outlines, red true legs, and a dark head.
Later still it becomes reddish-brown, with a partial dark line along the middle of the back, retaining the black and white spiracles. The caterpillar feeds on the foliage of :
The adult moth has grey forewings, with a broad pale stripe along the each wing, and a broad irregular dark band across the middle. The hindwings are mainly white with black wingtips.
The resting pose is unusual for Geometrids. The hairs on the thorax make a double crest that it can project forward over the head, and the moth folds its wings tightly along its back, making a wedge shape that tapers to a point at the end of the abdomen. The wingspan is about 5 cms.
The eggs are white with a dark dimple in the top, and are roughly spherical with a fine hexangonal embossed pattern. They are laid in a regular array.
The species is found over the south-eastern quarter of Australia, including
