Bees are positively charged and (this is wonderful) they are attracted to flowers with the strongest negative charges. I had always assumed that the reason pollen stuck to bees was because of their hairiness and the stickiness of the pollen. Well, that may be part of the story, but there is little doubt that static electricity is also important in the transfer from flower to pollinator. The negatively-charged pollen jumps onto the positively charged bee through electrical attraction.
