The adult is also green, and has two faint white zig-zag lines across each wing, and a yellow dorsal stripe on the abdomen. The termen of each wing and the costa of each forewing are pale orange. Because of the predominant green colour, this and related species of moths are called 'Emeralds'. The moth has a wingspan of about 3 cms. (ButterflyHouse)
I'm suggesting this is C. dichloraria for the following reasons after reference to the identification notes which may be found for these two species on the supporting disc for Moths of Victoria (Part 4). 1. The collar color :( the collar is the region between the head and the fillet (= base of the antennae). In C. dichloraria the collar is red (see image 2 for this specimen) whereas in C. melocrossa it is ochreous yellow or pale. 2. In C. dichloraria the outer margin of the hindwing is only slightly angled (as in this specimen), whereas in C. melacrossa it is more sharply angled. 3. In C, dichloratua the outer fringe of the forewings is described as yellow tipped with pink (as in this specimen) whereas in C. melacrossa it is yellow. 4. According to McFarland (1998). C. mele\acrossa never has red on the costa, however the original description describes it as 'costal edge reddish ochreous'. Whereas C. dichloraria typically has a 'pale costa with red at the apex and on the shoulder'. which looks consistent with this specimen.
The presence or absence of dots deems variable and is not used to distinguish these two species by Moths of Victoria Both these two species may have a black spots in both in hind and forewing but often they are quite faint. I think I can see at least one spot in your first image (RHS).
