The adult moths of this species have forewings that are pale brown with a variable complex pattern of scalloped darker brown lines and patches.
Unusually for moths in GEOMETRIDAE, the hindwings of this species are quite different from the forewings. The hindwings are orange with a broad brown margin and each has a dark spot in the middle. In the natural posture of the moth, these brightly coloured hindwings are obscured. The wingspan is about 4 cms.
The underside of each wing is yellow with a grey marginal band, a black submarginal band, and a black and white patch.
The species has been found in the southern half of Australia, including:
Another species superficially similar to, but genetically different from, Heliomystis electrica has been found in
