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 (http://jeb.biologists.org/content/213/4/ii.full)

Klaus,

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