Bees are used to pollinate the trees. As they fly from flower to flower, from tree to tree, pollen attached to the bees is transferred between trees which pollinates them, allowing them to produce fruit.
Bees stay close to the hive when rain is nearby because they can detect changes in air pressure. If is going to rain and the air pressure drops, the bees will remain in their hives.

Honey bees are kept in beehives by beekeepers but their natural habitat is in forests, usually within the hollow of an old tree.
Large bees that are eating tree bark are most likely carpenter bees. They bore holes in wood to lay eggs, which can harm trees. To deter them, you can paint or varnish the tree bark to make it less appealing, or hang fake wasp nests nearby to mimic a threat. Consider seeking assistance from a professional pest control service if the problem persists.
