Bees reign as the champions of pollinators, but some finicky plants demand the attention of bees that know all the right moves. Tomatoes, for example, receive the best pollination from bumblebees. Part of the tomato flower, known as the anther, will only release its pollen if it is vibrated. This process, called buzz pollination, requires bumblebees. Honeybees just don't shake their moneymakers the same way.
