The most distinctive forms have a greyish head, pronotum and ventral side, and the elytral markings reduced on the anterior half and blackish with violet reflections over a pale yellowish-cream background.
This species is related to, and appears to intergrade with, Castiarina flavopicta. Apparent intergrades have the head, pronotum and ventral sides more brightly coloured in metallic blue or green, sometimes combined with heavier elytral markings on a more yellow background.

Adults are associated with white nectar-rich flowers in which they feed, particularly Bursaria spinosa as well as a variety of Myrtaceae species.
A.M.P. Stolarski discovered this species breeding in the stems of a Daisy-bush species that is currently known in SA as Olearia ramulosa. The same genus is also used as a larval host by the closely related C. flavopicta.
