Castiarina adelaidae  Distinctive features

Ventral side yellow. Males in particular have very large and broad tarsi. Similar coloration to Castiarina decemmaculata with which it often occurs, but it is larger and has a broader body shape than that species.

Notes

This species was described by Hope 1846 'from the settlement at Adelaide'. It is similar and closely related to Castiarina octospilota of the eastern states.

It is a conspicuous spring species on Tea-tree (Leptospermum) flowers in the Adelaide foothills and central Hills area, as well as much further afield in places with heathy vegetation.

Forms from Kangaroo Island have heavier dark markings and often have two disjunct yellow lacunae in the anterior half of each elytron. On the mainland, forms with these lacunae conjoined are more common. Forms from the SE region have a richer yellow and stronger green reflections.
