Why do plants need pollinators?

Why? A quick refresher: pollen from a plant’s male anther needs to be transferred to the female stigma in order for a plant to reproduce via seeds. About 87 percent of flowering plants rely on pollination—and more than 150 food crops in the U.S. That’s where pollinators come in. They make the crucial exchange of pollen. Several species of animals help with pollination, including hummingbirds, butterflies, moths and wasps. But bees do the heavy lifting, transferring far more pollen than other animals. Although European honeybees and bumblebees are the best known of the U.S. bee varieties, our nation actually harbors more than 4,000 species of bees! Protecting undeveloped habitat for pollinators —such as wildflower meadows on the edges of farmland—is vitally important to protect these industrious, fruitful creatures.
