Possibly Northern Armyworm, but doesn’t seem to have the markings I’ve seen so far. This was the only one seen, so couldn’t compare to others at this time of year.
I caught this moth on 10/6/2024, at Kuranui Bay Reserve.
Dead, partial remains. Found inside cauliflower from grocery shop.
This seems like a really good match for the pattern, including relative positions of black and white scales, although not the brown appearance of the photo: https://oldwww.landcareresearch.co.nz/__data/assets/image/0003/98274/Eudonia_ustiramis3.jpg
The type photo though looks nothing like either: https://web.archive.org/web/20100518213213fw_/http://landcareresearch.co.nz/research/biosystematics/invertebrates/lepidoptera/cgi-bin/bug.pl?0450032?1740.0000
seems like a perfect fit to the larger moths photo
