The Minnesota Landscape Arboretum a part of the University of Minnsesota will open an exhibit in 2016 which will include a showcase about bee vision. Some of my Marsh marigold - Caltha palustris images will be used for this purpose, as these clearly demonstrate the difference between human and bee vision.

This Caltha flower has quite a prominent UV pattern: its center is UV dark, and has some UV dark veins on its petals and all this gets quite nicely visible.
I have written about this flower and how this was photographed HERE
Stay tuned, more will follow on that fascinating subject...
