Biting Stonecrop - Sedum acre in reflected ultraviolet photography and simulated bee and butterfly vision

Today shots of a decorative plant, a creeping Biting Stonecrop - Sedum acre in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

Quadriptych of human vision, UV, simulated butterfly and bee vision (left to right, top to bottom):
 

Sedum flowers have a distinct UV reflection, its petals have a quite UV dark center and the outside part is quite UV bright around 365nm and all this gets nicely visible, also in simulated bee and butterfly vision.

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

Missouri Coneflower - Rudbeckia missouriensis in reflected ultraviolet photography and simulated bee and butterfly vision III

Today shots of another Missouri Coneflower - Rudbeckia missouriensis hybride in reflected ultraviolet photography and simulated bee and butterfly vision. All shots were done at f8 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulated bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.
