I think this is a Orchid Tree, Bauhinia variegate. The honeybees were going crazy, it sounded like a whirling buzzing noise and the tree was covered with bees pollinating.
When the bees are out gathering nectar and pollen generally speaking they will not attack, if you bother them or swat at them they may defend and sting you but they are not in hive defense mode. A lot of people panic when they see a few bees on a tree or bush, the honeybees are just there to gather the fruit of their labor. The same goes with water areas, this could also be your pool or water fountain. Swarms occur and should be left alone, they will probably move on. Let them be and more than likely they will leave you be. We as humans can come into contact with bees daily so just take care and if you notice them coming and going from your home – just check them out and see exactly where they are coming from.
