The adaptive origins of the honeybee's age polyethism schedule were studied by testing whether the schedule for labor inside the nest reflects a compromise between efficiency in locating tasks and efficiency in performing tasks. I checked two predictions of this hypothesis: (1) at each age a worker handles a set of tasks (rather than one task), and (2) the elements of each age's task-set co-occur spatially in the nest (rather than being spatially segregated). Most observations match these predictions, once workers reach the age of 2 days. The unpredicted specialization of 0 to 2-day-old workers on the single task of cell cleaning may reflect an unusual ease in locating work sites for this particular task. There are 5 female castes in honeybee colonies: the queen (reproductive caste), plus 4 age subcastes among the workers (cell cleaning caste, broodnest caste, food storage caste, and forager caste).
