User's notes

This is the closest I can get with this one. I love the black spots in the trailing wing fringe. It does have a black spot on each of the wings.

Terrific photo of the underside. Well done.

This is not C. vertumnaria because this moth has no dorsal line on the abdomen. Moths of Victoria (supporting disc to Part 4) provide a comprehensive visual key to the Geometrinae. Several features I think are important in suggesting a likely identification of the species: 1. the single discal spots in both forewing and hindwing are black (ie. not both red or red and black) ; and 2. the termen of hindwing is slightly produced (a point) ; and 3. from above the termen of the hindwing and forewing show black spots. Lepidoptera Butterfly House shows and image of the underside of Chlorocoma externa which I think coincides with this specimen. The antennae are not branched suggesting its a female. Compare with Chlorocoma externa (Spotted-fringe Emerald) , CNM Sigthing No, 3872200.

The underside photo was easy since it was sitting on a grass stalk that it was too heavy for and so it had tipped upside down. It was getting the upper surface that was difficult and ended up with it walking onto my thumb. So I not only had to keep the camera steady but also my thumb.
I knew I wouldn't have the correct ID. But nice to know it is actually a Chlorocoma.
