Nectar is a sugar-rich liquid produced by plants. It is produced either by the flowers, in which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists providing anti-herbivore protection. It is produced in glands called nectaries. Common nectar-consuming pollinators include bees, butterflies and moths, hummingbirds and bats.
