Default Winter Aconite as we and insects see it

Winter Aconite (Eranthis hyemalis) in:
human vision, ultraviolet vision,
butterfly vision and bee vision
(simulated; left to right, top to bottom):


We humans see Red, Green and Blue,
butterflies see Red, Green, Blue and UV,
bees see Green, Blue and UV, but cannot see Red.

So what use is red to a flower that wants to get pollinated?

Hi Asher,

Maybe it's the lack of Blue (and maybe UV) and Green, that's important for pollination, not the remaining Red in our spectrum.

Cheers,
Bart

Butterflies and other insects DO see red and also bees have a complicated way of using red to detect a flower. Read here: http://jeb.biologists.org/content/213/4/ii.full

Klaus,

I meant for getting pollinated by bees that can't see red!
