Black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography and simulated bee vision XI

Today detail shots of a cultivar flower, originating from the USA Prairie, a Black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV filter. All shots were done at f8. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

This flower shows a very prominent UV bullseye pattern, as its petals are very UV bright (around 365nm) to about the middle and its center is very UV dark, and all this gets nicely visible also in simulated bee vision.

I have previously written about that flower HERE
 
Stay tuned, more will follow on that fascinating subject...
