Sighted on a handrail at ANBG's Rainforest Gully. It appeared to have remnants of a spider's web around its head. Not sure of the identification but assumed to be an immature moth.
The lack of markings on the head capsule are a problem for P. tristifica. For Ethmia clytodoxa see also https://inaturalist.ala.org.au/observations/336629577 https://inaturalist.ala.org.au/observations/336628550 I did check Don's site but I would never have looked at that group. Only one labelled record on iNat. Very interesting (rare) find Tim.
