While some species are solitary, the honey bees and the bumble bees are social insects. They form large colonies of thousands of insects, divided into three castes: the queen bee, infertile female worker bees and male drones. A queen will mate and lay eggs for as long as it lives, and in the case of honey bees this can be 2-3 years, sometimes 5.
Male drones exist only to fertilize the queen, and they soon die afterwards. Female workers also don’t live that much (up to 6 weeks), because they are constantly working for the survival of the hive. The hair on their bodies is crucial for pollination. They collect it from various flowers when sucking their nectar, and then leave it on others.
