This rare beauty was taken yesterday at a forest reserve. This was a lucky encounter as this specie normally make its appearance at dawn or dusk. The underwings shown here does not even give a hint of the glorious flourescent dark blue coloration of the top wings. Taken with Canon 300D using 75-300 mm IS plus 12mm and 20mm extension tubes. Camera set at 1/160, f10 with ISO 400. Sigma 500DG flash with Stefon omnibounce fired.
