Stingless Bees in Cambodia produce insignificant quantities of honey, but their larvae are relished by villagers. These bees—and there are a number of species, some of which can be seen in the Angkor Temple Complex—are important pollinators of forest trees, family fruit trees, agricultural crops, and grasses.
Bees Unlimited has introduced Stingless Bee beekeeping--using coconut shells for hives--to villagers, for their value as pollinators... and as a means of encouraging children to keep bees that actually sting.
