The Virginia Department of Agriculture and Consumer Services encourages the public to join in celebrating National Pollinator Week through June 25. Pollinator species such as honeybees, bumble bees, butterflies, and other insects are an essential component in the production of much of our food supply. Pollination occurs when insects, animals, wind, or water transfer pollen from the anther of one plant or flower to the stigma of another in the process of fertilization.
