Common Purslane - Portulaca oleracea in reflected ultraviolet photography and simulated bee and butterfly vision

Today in 2022 shots of a beautiful flower, now offered as an ornamental + edible plant, a Common Purslane - Portulaca oleracea 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 a modified Xenon flash.

This flower shows a very prominent and strong UV reflection around 365nm, and all this gets nicely visible, also in simulated bee and butterfly vision.
 
Stay tuned, more will follow on that fascinating subject...
