See Through My Eyes!
A very small sized Ricaniid Hopper, this possibly Plestia marginata is around 1.5 cm in wingspan. I cannot be 100% sure of the ID as I was told that it is hardly possible to ID them based on pictures. However, Plestia marginata is reported from Fiji.
Information I gather from further checking :
This genus has more than two dozen species primarily distributed in Oceania from Western Samoa to Fiji with a single doubtful record of the type species from "Nov. Holl." provided by Melichar. Its presence in Australia based on this record was doubtful. However the discovery of a single female specimen in ASCU from North Queensland confirms its presence in Australia. The genus is identifiable by the presence of four veins originating from the basal cell.
