Notes

A very common and widespread species occurring from south-west WA through to Qld. It is notably absent from Kangaroo Island, despite apparently suitable habitat there. This is a late spring to early summer species that is often found together with C. media. The emergence of these two Buprestids coincides with the peak flowering of Sweet Bursaria Bursaria spinosa, a principal adult host plant for them both.

Host plant notes

Castiarina larvae and prepupae were discovered in the basal stems of prostrate plants of Cranberry Heath Astroloma humifusum by A.M.P. Stolarski at a single site in the SE Region. From one prepupa I reared an adult (illustrated above) which, although it did not fully expand, can be identified with certainty as C. crenata based on the elytral patterning, aedeagus morphology and other features. This is the first breeding record reported for the species. There is not a lot that can be deduced from this one record, but as C, crenata is such a common species, it seem likely that it would use other larval host species also, at least other heath species in the same family, Ericaceae.
