Honey bees represent only a small fraction of the roughly known species of bees. Some other types of related bees produce and store honey, but only members of the genus Apis are true honey bees. The study of honey bees is known as melittology.
A swarm of bees settling on a roof is an omen that the house will burn down. If a bee enters your home, it's a sign that you will soon have a visitor. If you kill the bee, you will have bad luck, or the visitor will be unpleasant.
