Neocuris dichroa  Distinctive features

Two-tone colouration: the elytra variable in colour from brownish-red to purple or blackish-purple, sometimes with golden iridescence; the head, pronotum and ventral side generally green with some blue iridescence, or sometimes blue.

Notes

A common and widespread species. The adults have been found on a variety of plants and collected from nectar-rich Myrtaceae flowers. The discovery of their larval host came as a surprise.

Host plant notes

Breeding records of this species were first discovered by A.M.P. Stolarski in the bases of Small-leaf Eutaxia Eutaxia microphylla) plants. They have proved to be very common in this species over a wide area. They have now also been found in the only other {Eutaxia species in SA, Long-leaf Eutaxia E. diffusa, as well as in a population of putative hybrids between the two species near Callington.
