Chlorocoma undescribed species MoVsp3 (An Emerald moth)

Chlorocoma dichloraria, vertumnaria and melocrossa are difficult to distinguish.  They each have faint white wiggly lines on the forewing, a yellowish-white line running along the top of abdomen, and a variable degree of red on the fringes of the forewings.  Their separation in CNM is done mainly by using the criteria on the CD accompanying Moths of Victoria Part 4. Chlorocoma melocrossa is bluish-green with a broad yellow fringe, sometimes with touch of red at the apex or base of the forewing; the fringes of C. vertumnaria are yellow on the inside, and red on the outside encompassing a row on black dots in fresh specimens; and C. dichloraria is apple green with a less prominent red outer fringe.

There are other Chlorocoma present in the ACT and they have other distinguishing criteria, most of which are covered in Moths of Victoria.   In particular, C. vertumnaria and C. undescribed species MoV3 are separated by the line along the top of the abdomen being plain yellowish-white in the former, and having some red in the latter.
