Cliff maids - Lewisia cotyledon in reflected ultraviolet photography, simulated bee and butterfly vision VII

Today in Summer of 2021 more shots of a  pink long blooming (2nd bloom), perennial flower Cliff maids - Lewisia cotyledon in reflected ultraviolet photography and simulated bee and butterfly vision. All shots were done at f11 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 Xenon light from my UV enhanced studio flash.

Lewisia has a visible UV pattern, its petal tips are UV bright around 385nm, its center is UV dark, so this gets quite nicely visible, also in simulated butterfly and bee vision.

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