Abstract : Drones and workers have completely different roles in a honeybee colony. This is reflected in many physiological, morphological and behavioural differences. Our overview mainly focuses on aspects of diet and metabolism in larvae and adults, and on the physiology of digestion. As larvae, drones have different protein and sugar requirements than workers, and in each life stage drones and workers differ in body composition percentages of glycogen, lipids and proteins. Like queens, drones as adults are nourished by worker-prepared food, and compared to workers their ability to digest is reduced. Mature drones fly usually only under optimal weather conditions. Their flight metabolism and resting metabolism also differ from those of workers. We discuss these differences as adaptations to the different functions of the two sexes within the colony as a superorganism.
