Two-tone colouration: the elytra vary in colour from brownish-red to purple to purplish-black, often with some gold reflections, while the head, pronotum and ventral side are most often metallic green (with some blue iridescence marginally), but may also be gold or blue.
A common and widespread species, although I have only occasionally encountered adults in the field. However, I have obtained numerous records of this species from coloured lures and as breeding records from its larval host plants. The relatively few field collections have been made either on nectar-rich Myrtaceae flowers (as is typical for the genus) or on the foliage of several unrelated plant species. By far the highest record count comes from green lures (with blue ones a distant second). This suggests an attraction to foliage, but it is probably more about finding mates, since there is preponderance of males and very few females, recorded in this way.
The discovery of this species' larval host plant came as a surprise.

| estimate of active beetles, inferred* from adjoining date ranges |

| actual count <= 1.5 (median) |
| inferred* active beetles only (mostly from colour lure trap results) |
| live non-emerged (inactive) beetles only |
| *Inferred when a site has counts of active beetles for each of two consecutive
periods (date ranges), one finishing and the other starting in the same
quarter-month. The count estimate is assigned to that quarter-month and calculated
as the lower of the two total beetle counts, divided by the number of quarter-months
in its date range.
Assumes that beetle activity is essentially continuous within a single active period per year, and that date ranges do not bridge a non-active period (thus only ranges of < 4 months are used). |

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 of SA. 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.
