 This, along with the consequential pairing of the high relatedness rates within colonies of "S. quadripunctata", serves to explain the high degree of kin selection among stingless bees.After a female queen mates and lays her brood, the worker bees package them into specifically designed cells – queens in larger “royal” cells and workers and dwarf queens in smaller ones.Each cell is then capped with a layer of wax-like substance.
