Tetragonula Biroi is stingless be endemic to Sulawesi island of Indonesia, only 2 kilograms a year honey per colony can produce. The honey contain a magical thing called propolis. Look at my picture above, The bees store pollen and honey in large, egg-shaped pots made of beeswax (typically) mixed with various types of plant resin and propolis. This combination is sometimes referred to as "cerumen" (which is, incidentally, the medical term for earwax).
Stingless bees, sometimes called stingless honey bees or simply meliponines, are a large group of bees (about 550 described species), comprising the tribe Meliponini (or subtribe Meliponina according to other authors). They belong in the family Apidae, and are closely related to common honey bees, carpenter bees, orchid bees, and bumblebees. Meliponines have stingers, but they are highly reduced and cannot be used for defense, though these bees exhibit other defensive behaviors and mechanisms. Meliponines are not the only type of "stingless" bee; all male bees and many female bees of several other families, such as Andrenidae, also cannot sting. Some stingless bees have painful and powerful bites.
