If you see honeybees swarming on a tree, please don't spray them with a hose, call a local beekeeper and they'll gladly come and remove them for you. Honeybees are valuable pollinators, we can afford to lose a single hive.
What that swarm on the tree is called is a reproductive swarm. They gather up honey and fly away from their home with a queen. They settle somewhere to then go out and find a new home. They won't stay there, they've sent out scouts who are actively looking for a new home. Once it's found, they'll all lift off and leave. Swarms are not dangerous, they are a natural cycle of a honeybee hive.
