An attractive insect, up to 12 mm long with a black head and bands on the fore-wing, and orange/red elsewhere. When the wings are folded, two red triangles appear. Legs are relatively long.[2]

The New South Wales Department of Primary Industries (Agriculture) report they attack cotton, pome fruits, stone fruits, fig, grape, kurrajong, strawberry, vegetables, wisteria, dahlia and violets.[3]
