Rockfoil - Saxifraga in reflected ultraviolet photography and simulated bee and butterfly vision II

Today shots of some beautiful little red flowers Saxifraga - Rockfoil in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as in simulated bee and butterfly vision using my XBV filters. All shots were done at f11. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

Human vision:
 

Reflected ultraviolet (UV):
 

Simulated butterfly vision:
 

Simulated bee vision:
 

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

This flower shows no very prominent UV pattern, its petals transparently shine somewhat in UV (around 385nm), and all this gets nicely visible, also in simulated bee and butterfly vision.

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