This Caterpillar is green with a white line along each side. It only has the final two pairs of prolegs, so walks in a looper fashion. It is known to feed on various trees in MYRTACEAE including:
The adult moths of this species have forewings that have a complex pattern of black, white, green, and pale brown. The hindwings are green, shading to brown along the costas. The females have whip-like antennae, and the males have feathery antennae. The wingspan is about 3 cms.
The brown coloration is mainly limited to four areas: along the costa, at the wingtip, and two areas near the middle of each forewing. Some specimens have all four brown areas (as in Peter's specimen below), some only have the latter two near the middle of each forewing (as in Donald's specimen above). There appears to be no correlation between the number of brown areas and the sex or location. The green coloration appears to fade in older dead specimens.
The underside is pale grey with a well-defined narrow zigzag submarginal line plus other ill-defined bands of black and red across each wing.
The species is found in
