Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography and simulated butterfly and bee vision XXVI

Today first shots of a very decorative summer flower in 2016, Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated butterfly and bee vision using my proprietary XBV filters. Lens was my UV-Nikkor 105mm quartz flourite lens. Light source was sunlight. All shots were done at f8.

Mexican Zinnia flowers have a very specific UV pattern. Their petals are very UV dark in the middle and bottom, their petal tips, however, are very UV bright (around 365nm outer tip), and all this gets nicely visible, also in simulated bee and butterfly vision.

Mexican Zinnia flowers have a very specific UV pattern. Their petals are very UV dark in the middle and bottom, their petal tips, however, are very UV bright (around 370nm outer tip, 365nm middle tip, 350nm border to dark), reaching deeper into UV as any other flower I know of, and all this gets nicely visible.
