POLLINATORS A pollinator initiates fertilization of a plant by moving pollen from the male anthers of a flower to the female stigma of a flower. Once fertilized, a plant will produce fruit and/or seeds that will lead to plant reproduction. Pollinators include ants, bees, wasps, beetles, butterflies, moths, and hummingbirds to name a few
