Orange coneflower - Rudbeckia fulgida in reflected ultraviolet photography and simulated bee vision III

Here more shots of that decorative flower meadow made of Orange coneflower - Rudbeckia fulgida var deamii in reflected ultraviolet using Baader-U filter and in simulated bee vision using my XBV6 filter. Lens was a 55mm Dialyte lens. Light source was sunlight. All shots were done at about f8.

This attractive flower has a very specific UV pattern, its petals form a UV dark bullseye pattern, invisible to us humans and the flower center is quite UV dark, and all this gets nicely visible.


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