The honey bees naturally work together to produce honey. This teamwork often creates a festoon or a bridge made from bees within the open spaces in the hive. Bees use their own bodies to create a living bridge for other bees to use to cross into a frame. The six legs of the honey bee have pads and hooks so they can "hook" onto another bee's hooks. They build their own scaffolding for a several reasons. They use this festoon when swarmming and hang onto a tree limb or another object. Bees also festoon to hang out of the hive entrance in warm weather. A large number of bees create ventilation of the brood nest by festooning outside of the hive.
