Individually labeled freshly emerged honeybee workers (Apis mellifera) from three unrelated source colonies were introduced into five host colonies. The location of the workers during their first eight days of life was monitored. Workers from the same source colony tended to be found more often in the same area of the comb than workers from a different source colony. Although kin recognition among workers cannot be ruled out as a possible mechanism for this pattern, the results can be more readily explained by phenomena related to self-organized pattern formation, individual behavioral threshold variability and genetically determined worker task specialization.
