Integrating the phenology of pollinators and their food plants is crucial to understand pollination guilds. In the tropics, studies on the phenology of the trees and of pollinating vectors such as bees have mostly been carried out independent of each other. This study, carried out at a wet evergreen forest of Kakachi, in Southern Western Ghats, integrates the phenology of two social bee species Apis dorsata and Apis cerana with their canopy and sub-canopy food plants. The two bee species are the only ones that are active on the canopy of this forest and visit the under storey plants occasionally (Davidar et a1., unpublished). Unlike other tropical forests, solitary bees are distinctly
absent in this forest canopy, and therefore the two bee species playa major role in the pollination of a number of tree species in the forest.
