Instantly recognisable by the eight major spots on the orange-coloured elytra. In the South-east of the State the spots tend to be larger and the background a richer and darker red-orange.
The type of this species is from Adelaide. It was first described under (under Stigmodera) by Saunders 1868b who gave its habitat as 'Adelaide'. In spring, it is common on Leptospermum flowers in Stringybark and sand heath plant communities of the Adelaide Hills, southern Mt Lofty Ranges and South-eastern regions, and also occurs widely across south-eastern Australia. Notably it is absent from Kangaroo Island where similar plant communities occur.

9 | number of active beetles, actually recorded in that quarter-month | |
2 | estimate of active beetles, inferred* from adjoining date ranges | |

| actual count <= 43 (median) | ||
| *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. | ||
