Gonepteryx cleopatra "Cleo" butterfly on Rudbeckia hirta: human vision; UV ultraviolet stimulated visible fluorescence photography

Here now after having shown it in bee vision and reflected ultraviolet photography that Cleo butterfly Gonepteryx cleopatra or Cleopatra, resting on a Rudbeckia hirta flower. Now here shown in normal visible as well as UV induced stimulated visible fluorescence, using various UV sources as well as blocking filters (BG38, Baader UV/IR CUT filter).

Nice results and a a lot of details on the wings gets visible using fluorescence method, yet personally I prefer reflected UV photography.


Stay tuned, more will follow on that fascinating subject...
