We have cases in Australia that bees working certain flowers are often 
deemed to be more cranky than when working others.  Examples of bees getting 
cranky on certain flowers are spotted gum and tea tree.  I know in our case 
for tea tree that bees will be not happy on the tea tree site but when you 
shift them away, within a day or so, they are quite gentle.

Peter, you certainly come up with some interesting subjects. It is 
appreciated.
