@ibaird I thought it was close to Plectophila sp. ANIC16 https://bold-au.hobern.net/specimens.php?taxid=365434 but maybe this is misplaced and should be in Iulactis
It looks pretty close to Iulactis semifusca (except for 2 thorn like marks, tan on palps and below eye) the long white mark is a better match than on Plectophila sp. ANIC16 see https://xyloryctinemothsofaustralia.blogspot.com/search?q=Iulactis+semifusca https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/57c7f279-d79e-4522-ae1a-27ed8b697bd6
I see only one complete white chevron on the forewing, not two as in the images of I. semifusca that I have seen. Maybe the species is dimorphic and I have only seen the other sex?
