#499 - Nagia linteola? EDIT: Donuca spectabilis
EDIT: It’s not Nagia - It’s a Donuca species found over much of Australia, where the larvae eat a common wattle.
I'm pretty confident this is Nagia linteola. The problem with that ID is that I can't find any mention of the species being found anywhere NEAR Perth. It's known from South Africa, the Congo, Yemen, the Comoros Islands and Mauritius, and ALA has sightings from coastal areas across Australia's top end and down the Queensland coastline, but none over here.
Although I suppose there's no reason why it wouldn't be here - it's known to breed on Crepe Myrtle (a popular ornamental tree from China that thrives in Perth), various Native Almonds and Native Damsons in the genus Terminalia, and possibly Morton Bay Ash (a eucalypt). I'm just reluctant to be the first to report it from here.
My porch, Wellard, but I've seen the same species at the Baldivis Spud Shed as well.
