White honey
L.chandrai is found in cut stone mounds, building foundations and tree trunks in Kannur and Kasaragod districts Kerala. The hives have a very small entrance. There are always two servants on guard. If disturbed, they will leave the queen and fly away. L.chandrai adopted the method of storing pollen on one side of the brood and honey on the other. Their eggs, pollen, and honey are white, so they are called white bees. These micro-colonies collect very little honey per year. Generally,honey bees produce 250-500 ml of honey a year, but L.chandrai produce one teaspoon of honey a year. Culturing of stingless honey bee is known as meliponi culture. It is one of the oldest farming adopted by human beings. There are bees that give up to 5000 grams of honey per year. White honey is an excellent nutrient and medicine for various ailments.
