An interesting variety of the flower-bee interaction recently has come to light, see for example

I wonder whether our old enigmatic friends, the conical cells, have a role in such phenomena?

How remarkable!! I just read an article in Chemistry in Australia which referred to the same original research - so it must be true

Here's a link to the original (2013) paper which also has some very interesting links to subsequent work

It just goes to show that we will never know how a pollinator really senses and interacts with the environment, some one will always find a new angle we didn't foresee.
