Abstract

The social organization of insect colonies has fascinated biologists and natural historians for centuries. Aristotle wrote in History of Animals about a division of labor among workers within the hive that is based on age. He observed that the field bees foraging for nectar and pollen have less “hair” on their bodies than the hive bees that care for young larvae and tend the nest. He concluded that the more pubescent hive bees must be older. We now know that, in fact, the field bees are older and have less hair because the hairs break off as the bees age. The phenomenon of age related changes in behavior, age-polyethism, is now well documented for many social insects (Oster and Wilson 1978).Evidence of the ecological success of social insects is inescapable. Virtually everywhere you look you see them or the results of their activities.
