Houston, we have a problem. An identical moth to this [ Sighting 4645827 ] has been IDed as Labdia argophracta see https://bold-au.hobern.net/specimen.php?processid=ANICW1769-11 https://bold-au.hobern.net/specimens.php?taxid=326537 sadly there are aspects of both that don't quite fit with the 2 species live specimen records. I need to do some more research on this to see if I can offer any suggestions.
my 1st puzzle solved from Monographs Aust. Lepidoptera Vol. 11 CSIRO - the form of E. flammula similar to above is the female. The male (see https://bold-au.hobern.net/specimens.php?taxid=326537 ) has white forewings with a dark central stripe along most of their length
