Arrowwood - Viburnum bodnantense in reflected ultraviolet photography, simulated bee and butterfly vision

Today still in cold January 2024 shots of a blossoming Arrowwood - Viburnum bodnantense bush 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 a modified Xenon flash.

Arrowwood bush flowers have no distinct UV reflection pattern, but their stamen create a UV dark center important to attract UV seeing pollinators and this gets nicely visible here, also in simulated bee and butterfly vision.
