I was shocked when I saw five different types of bees on a blackery bush at 
the same time, from bumblebee down to one so small you can hardly see it. 
One small one had a green head (what is that?). My honeybee was there also.
 So I don't think a home gardner would need honeybees for pollination here 
in Maine, but buleberry farms is another story.
