Notes

This is a late spring to early summer species that is often found together with C. crenata. The emergence of these two Buprestids coincides with the peak flowering of Sweet Bursaria Bursaria spinosa, a principal adult host plant for them both.

The Mt Lofty Ranges populations of C. media tend to have heavier dark markings on their elytra compared to those on Eyre Peninsula, and to those on Kangaroo Island, especially, where the posterior fascia is may be reduced to two widely separated small patches.
