Two arrivals last night after I had finished posting, however I had to try and identify, so today is the day for popping them up. One is identified and the other is still a UFO.
The identified flyer is of the Geometrinae family cyneoterpna wilsoni with the underwing markings making it a standout identity.
However I am as yet stumped on the UFO even though you would think the distinctive colouring and markings would make the ID a sitter, so I will be pleased if anyone can put a name to this character.
