Scaptesyle monogrammaria!! completely wrong I meant to say, Thallarcha jocularis (Rosenstock, 1885), which I believe it is. Hence the white background see Sighting 4660207
A new specis for NatureMapr and NatureMapr's New Englnad region if confirmed. Apparently Thallarcha chrysochroa 'Golden Footman' although the base forewing colour is white rather than golden yellow in this instance. See here:- https://lepidoptera.butterflyhouse.com.au/arct/chrysochoa.html
