If you were a flower ....

...and you want to make sure bees would find you, would you look like this?



Well another one of my "bee vision" series, so what you see here is UV+Blue+Green, in this case a Rudbeckia fulgida. The petals are all yellow, no visible pattern and the center is pitch black ("Blackeyed Susan") - well ,only to the human eye...

[Maybe I should say a bit more about this: Grass and foliage also reflect a lot of UV. So "just" having a high UV reflection doies not help a flower much to be found by its pollinators - it needs a bit more "creativity". So how to make sure to stand out of the crowd? Some flowers found a tricky way, they create a "landing platform" for bees and bumble bees, consisting of concentric rings, like that white and another green one. And inside there is that bright UV reflective center. But only with the help of these contrasting petals around it stands it out. But why is that invisble to us humans? Very simple actually, since nature is so efficient: we don't pollinate flowers, so why should the flower develop something visible to us?]

Very interesting Klaus, indeed it looks like a landing platform.
Thanks for the explanation.

Watch out for the forthcoming BBC1 Series "Invisible Worlds" in Spring 2010 - there will be more to see about my work....

Most welcome guys! I know it is quite a bit exotic, but since I use manual lenses for that, I thought I could share that a bit with the community here...

Your bee vision series is quite fascinating. I had never considered the way other life sees the world. Thank you for opening my eyes just a little wider than before Smile
