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 :D

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

Detection and learning of floral electric fields by bumblebees

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.

We should see, and learn, what UV signatures are for their own sake.

Reading 'meaning' into Nature's many manifestations is a futile exercise.

Well, as you probably guessed, Colin, this is neither "corona" nor "aura" ;)
