How the honey bee regulates its body temperature


Bernd Heinrich


Honey bees are able to forage over a 30°C range of air temperature largely because they have behavioural and physiological mechanisms for regulating the temperature of their flight muscles. From very low to very high air temperatures, the successive mechanisms are shivering before flight and stopping flight for additional shivering, passive body temperature in a comfort range that is a function of work effort, and finally active heat dissipation by evaporative cooling from regurgitated honey sac contents. The body temperatures maintained differ depending on expected foraging rewards and on caste.
