I was sad to find that, after being alive in the morning, this exquisite creature had died by the time I came to photograph it properly, a few hours later. My sincere apologies if photos don't enable IDing
For notes identifying features separating Chloroclystis filata, and Chloroclystis pallidiplaga/Pasiiphodes testulata see pp. 196-7 of 'Moths in the ACT' (Cocking et al (2022). ie.: "C. filata 'is very common and can be recognised by the dark patch inside the apex of the forewing, and in some specimens there is also a white patch extending inwards from near the inner margin (see arrows on photos p. 196). Chloroclystis pallidiplaga (or Pasidiphilodes [Chloroclystis] testulata, a very similar species) usually has two distinctive white patches on the forewing in different positions from the white patch that can occur on C, filata." (These different white patch positions are illustrated on pp. 196 and 197 for the two different species).
