Sorry, John, its a bit difficult to tell whether this is a Scarlet or Wandering Percher. The Terminalia are not clear, the colouration is just starting to develop, the shape of the abdomen is not definitive, and the apparent brownish smudge at the base of the hind wing could also be some of the background showing through. There are some features that seem to indicate Scarlet , but others that are more suggestive of Wandering. Going to have to leave it as unidentified Diplacodes percher.
