Emerald Moth

I am also thinking this may be Oenochroma infantilis, but the hindwings do have curved wings, which could suggest Mixocera.

I think it might just be variation or the same genus--Mixocera latilineata, or Mixocera katilineata--the only members of the Mixocera genus in Australia, as reported by BOLD: http://www.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxon=Mixocera&searchMenu=taxonomy&query=Mixocera

Okay! :-) You might remember them.... http://www.projectnoah.org/spottings/19659003

Beautiful, Christiane! Are you looking for an ID for the three largest ones?
