Nectar is a sugar -rich liquid produced by plants in glands called nectaries or nectarines , either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries , which provide a nutrient source to animal mutualists , which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes , hoverflies , wasps , bees , butterflies and moths , hummingbirds , honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, A. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps e.

Did You Know?
Nectars are a type of non-carbonated soft drink made by muddling the flesh of fruits. In some countries, the beverage industry distinguishes nectars from drinks labeled as "juice". From Wikipedia, the free encyclopedia.
Nectar , sweet viscous secretion from the nectaries , or glands, in plant blossoms, stems, and leaves. Nectar is mainly a watery solution of the sugars fructose , glucose , and sucrose but also contains traces of proteins, salts, acids, and essential oils. Sugar content varies from 3 to 80 percent, depending upon such factors as plant species and soil and air conditions. The production of nectar as a food reward for animals is a classic example of coevolution. Nectar in flowers serves chiefly to attract pollinators, such as fruit-eating bats , hummingbirds , sunbirds , and insects. Nectaries are usually located at the base of the flower stamens , which draw animal visitors into contact with the pollen to be transferred.
