<P> Nectar is a sugar - rich liquid produced by plants in glands called nectaries , 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 antiherbivore protection . Common nectar - consuming pollinators include mosquitoes , hoverflies , wasps , bees , butterflies and moths , hummingbirds , and bats . Nectar plays an important role in the foraging economics and overall evolution of nectar - eating species ; for example , nectar and its properties are responsible for the differential evolution of the African honey bee , A. m. scutellata and the western honey bee . </P>
