1. The pollinating efficiency of honeybees and bumblebees when visiting red clover flowers was determined. 2. The percentage of florets visited that set seed decreased rapidly with the number of days they had been open. 3. There was little or no difference between the pollinating efficiency of honeybees and different species of bumblebees when both entered the florets. 4. The number of florets visited per head varied with the availability of nectar and pollen. Pollen-gatherers tended to visit more florets per head and to be more efficient pollinators than nectar-gatherers. 5. The percentage of visited florets that set seed did not vary with the number visited per head.
