Pollinators are animals (biotic vectors) that move pollen from the anthers of one flower to the stigma of another, allowing for fertilization to take place. Examples include some birds, bees, moths, and butterflies (such as the one pictured above). Pollinators play an important role in their environments as they assist in providing genetic diversity to flowers by spreading their genetic material in ways that abiotic vectors such as wind and water cannot. As a butterfly drinks the nectar of a flower, some of the flower’s pollen sticks to the butterfly’s hairy feet. The butterfly then deposits this pollen on the stigma of another flower.
