Abstract
Introduction Reproductive hierarchies are typical for insect societies. In the socially most advanced species, a queen dominates her daughter workers which help to raise the queen's offspring. Reproductive division of labour is particularly strict in honeybee colonies, Apis mellifera. The queen is the only reproducing female and the workers actively eliminate the few eggs which are occasionally laid by other workers, a process which has been coined "policing" (Ratnieks and Visscher, 1989). Queens, however, are not immortal. After loss of the queen, the honeybee colony usually rears an emergency queen from the young female larvae in the colony.
