Diphucrania nubeculosa Distinctive features
A relatively large Diphucrania species with the females generally purplish and the males smaller with green head, pronutum and ventral side.
Notes
The strong sexual differentiation in this species led to the females and males being originally described as two separate species. Based on specimens from Adelaide,Germar 1848 (pp.176-77) named the female Ethon nubeculosum and the male E. chalcopterum. Carter 1923a (p. 165) pointed out that they were the same species, and this was confirmed by Barker 1999a when he examined the types in the Humboldt University Museum, Berlin.

Host plant notes
Adults are common foliage-feeders on Golden Wattle Acacia pycnantha and other Acacia species in SA. Breeding has only been established in one rather localised host plant species to date (A. spilleriana), but given the abundance and distribution of D. nubeculosa, it is likely that A. pycnantha and other Acacia species will be shown to be larval hosts also.
