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.

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...
