Bees are flying insects closely related to wasps and ants.  Bees are known for their role in pollination, as well as, for producing honey and beeswax. There are nearly 20,000 known species of bees in seven to nine recognized families, though many are undescribed and the actual number of species is probably higher. Bees are found on every continent with the exception of Antarctica and in every habitat on the planet that contains insect-pollinated flowering plants.
