Photo take at home this small bees are very common i seen them everyday i have two tree with flowers they love very small about 7 mm long brown abdomen and black head and legs.They belong in the family Apidae, and are closely related to common honey bees, carpenter bees, orchid bees and bumblebees. The common name is slightly misleading, as a great many other bee species, especially in the family Andrenidae, are also incapable of stinging, as are all male bees. Meliponines have stingers, but they are highly reduced and cannot be used for defense.
Stingless bees can be found in most tropical or subtropical regions of the world, such as Australia, Africa, Southeast Asia, and tropical America. Wikipedia.
Mayan people use to make hollow trunks to use as a hive and get the precious honey.
