Head with a strongly depressed frons, sides of pronotum and posterior elytra with areas of dense white scale-hairs, midline with coppery to gold reflections, and abdominal ventrites with bluish reflections.
With unusual blotchy white and dark grey-bronze patterning, this species appears to be camouflaged by its resemblance to a small bird dropping when sitting on its host plant.

The discovery of adult host records in SA, two from Native Cherry Exocarpos cupressiformis and another two from Slender Cherry E. sparteus (illustrated here for both hosts) led to targeted searching of Exocarpos for evidence of larval host usage. A.M.P. Stolarski discovered the breeding records in E. sparteus presented here, which are the first for that host species and for SA. Turner 2001d found it breeding in E. cupressiformis in NSW.
