Rudbeckia fulgida var deamii in visible and UV light

Today about another attractive flower, for humans as well as bees: Rudbeckia fulgida var. deamii. Shot outside with natural light (blue sky, no direct sun) in visible and ultraviolet light, using the Baader-U UV pass filter, a CERCO 94mm quartz flourite lens and my UV sensitive camera.

The petals of this R. deamii variant shows a very distinct "bullseye" UV pattern, invisible for us humans, as many other Rudbeckia species do. Also this one is reflecting around 365nm at its petal tips and is creating a very distinct UV nectar guide for its pollinators.

Wow, that's amazing! I didn't know the difference between what we see and what a bee sees can be so big.

Yes, it indeed is. My Blog has many more examples for that [url]uvir.eu[/url]
