Right at the end of our stay in Khao Phanom Bencha, this small lycaenid came down. This is the only shot I managed. It refused to allow me a side shot, flying away every time I raised the camera, although I was able to get a good view of it so am very confident of its identity. I waited for 1/2 hour for it to return until Antonio told me it was time to go.
One small hint, it is not found in Singapore, and it is considered very rare.
