Whenever CarnonAI suggests Aelothapsa malacella it has almost always been wrong in recent weeks. Not the first time it has misidentified this species as Alelothapsa malacella.
There are only a handful of moth species that CarbonAI routinely identifies correctly. Each moth suggestion by CarbonAI needs to be doublechecked. This is not supprising because there are literally thousands of different moth species in Australia (many unidentified) and only a relatively few correctly identified ones for CarbonAI to learn!
It doesn’t look like M. occidentalis which I have found a few times before in WA. M. simplex is a possibility. I’ll have a look at my reference collection when I am back home in a few days
Looking at iNaturalist could it be M. occidentalis? There aren't any records on iNat outside SA though. I didn't get a photo but the thorax was bright metallic blue.
