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

Today more shots of a very decorative summer flower, 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 CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

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.

I have previously written about those Zinnias HERE

Stay tuned, more will follow on that fascinating subject...
