(Specimen: courtesy of the Macleay Museum, University of Sydney)
These Caterpillars are initially yellow, later becoming green, with a darker line along the back. The head is initially black becoming brown then green, and developing a pair of short horns. The caterpillar feeds on :
both of ELAEOCARPACEAE.
The caterpillars often build a silk shelter under a curled leaf on the foodplant or on the ground nearby, in which they rest when not feeding.
The pupa is green with a length of about 1.5 cms.
This adult moth is brown with several small white spots on the forewings. Its wingspan is about 3 cms. It is a rather boring butterfly, but it has an unusual natural posture: the wings are extended downwards below the thorax so that the undersides are touching. The wingspan is about 3 cms.
The eggs are pale brown, ribbed, and dome-shaped. Their diameter is about 0.8 mm. They are laid on the young shoots of a foodplant.
The species occurs only in Western Australia.
