Castiarina decemmaculata  Distinctive features

Readily distinguished from C. parallela and C. xanthopilosa by the pale yellow ventral side, and from the related C. malleeana by the purplish-bronze head and pronotum, and the metallic purple marks and leg colouration below (in C. malleeana these areas are violet, green or blue).

Notes

A common species in the Adelaide Hills on Heath Tree-tree Leptospermum myrsinoides and also extending into semi-arid areas on sandy soils with heathy vegetation.

Host plant notes

Adult hosts are almost confined to plants of the Myrtle family (Myrtaceae) and largely found on Tea-trees Leptospermum spp., particularly Heath Tea-tree L. myrsinoides. A.M.P. Stolarski is the discoverer of the breeding records for this species.
