Looking again at this specimen, looking particularly at the thorax area from above in plan view (ie second photo), on second (and third) thoughts(!), I do not think this moth is a particularly good match for either Liestarcha amphigramma or Eulechria autographa. The specimen here has a black central line for the thorax. When looking at L. amphigramma or Eulechria autographa on both INaturalist and Bold (Hobern) those species do not seem to show that feature.. However Bold (Hobern) shows there many are unnamed Leistarcha (genus) variants which do show black central lines (with several different thorax patterns). I note iNaturalist's ID algorithm will select L. scitissimella when fed the second photograph. I am therfore suggesting Leistarcha (genus) whould be a valid ID for this moth given the apparent variation amongst unnmamed Leistarcha species on BOLD (Hobern). https://bold-au.hobern.net/specimens.php?taxid=93257
Thanks, @Tapirlord. Sorry, it was the creeping mistletoe I was thinking of. But that's not right either. I lost the edit function for a while. Back again now.
