✦ Synopsis

A model of pollination, having one species of bee and several species of flower, is presented. The foraging bee monitors the size of the nectar standing crops of the various flower species and, using a learning procedure described in the paper, tends to visit more frequently the species with the larger nectar standing crops. The differential visitation rates affect the relative reproductive success of the flower species. Steady-state flower distributions are derived and it is proved that such equilibria exist. The model explains some general features found in the pollination market, such as why bees lack innate preferences for certain flower species, the equilibrium allocation of flower resources between display and reward, and the conditions that permit deceptive flowers.
