 Bumblebees do not exhibit the " bee dances " used by honeybees to tell other workers the locations of food sources . Instead , when they return from a successful foraging expedition , they run excitedly around in the nest for several minutes before going out to forage once more . These bees may be offering some form of communication based on the buzzing sounds made by their wings , which may stimulate other bees to start foraging . Another stimulant to foraging activity is the level of food reserves in the colony . Bees monitor the amount of honey in the honeypots , and when little is left or when high quality food is added , they are more likely to go out to forage .
