The highly social honey bees and stingless bees build complex nests for protection to rear their young and to store their food.
Stingless bees defend themselves by constructing a strong nest wall and entrance tube, and with guard bees that bite and daub resin on their intrders.
Keeping native stingless bees is a hot topic in Australia for commercial, environmental and recreational reasons. You can do something about the decline of pollinators by conserving native bees.
As pets go, stingless bees have many benefits and few downsides.
There are no stings attached. They do not produce any venom, and are incapable of causing any serious allergies. In fact, they are entirely harmless, making them perfect as an educational resource in kindergartens and schools.
