Macrophotograph of the honey bee, Apis mellifera on the flower of the ox-eye chamomile, Anthemis tinctoria. The pollen basket, loaded with pollen to be taken to the hive, is visible on the bee's knee. Its tongue is extended as if drinking nec- tar. While gathering pollen and nectar the bee transfers pollen from the anther of one flower to the stigmatic surface of another. If compatible, fertilization and seed production follow. x 1.25
