Nectar is derived from [[Latin]] ''nectar'', the favored drink of the gods, which in turn is the Latinized version of [[Greek]] νέκταρ, ''néktar'', presumed to be a compound of the [http://en.wikipedia.org/wiki/PIE PIE] roots ''nek''-, "[[death]]", and -''tar'', "overcoming", i.e. has a similar etymology to [http://en.wikipedia.org/wiki/Ambrosia ambrosia], the [[immortality]]-conferring food of the gods. The earliest recorded use of its current [[meaning]], "sweet liquid in flowers," was in AD 1609.

'''Nectar''' is a [http://en.wikipedia.org/wiki/Sugar sugar]-rich liquid produced by plants. It is produced in glands called ''nectaries'', either within the flowers in which it attracts [http://en.wikipedia.org/wiki/Pollination pollinating] animals, or by ''extrafloral nectaries'' which provide a nutrient source to animal [http://en.wikipedia.org/wiki/Mutualism_(biology) mutualists], which in turn provide [http://en.wikipedia.org/wiki/Plant_defense_against_herbivory#Indirect_defenses anti-herbivore protection]. Common nectar-consuming pollinators include [http://en.wikipedia.org/wiki/Bee bees], [http://en.wikipedia.org/wiki/Butterfly butterflies] and moths, [http://en.wikipedia.org/wiki/Hummingbird hummingbirds] and bats.

Nectar is an ecologically important item, the sugar source for [http://en.wikipedia.org/wiki/Honey honey]. It is also useful in [[agriculture]] and horticulture because the adult stages of some predatory insects feed on nectar such as almost all solitary wasps. In turn, these wasps then hunt agricultural pest insects as food for their young. For example, thread-waisted wasps (genus ''[http://en.wikipedia.org/wiki/Ammophila_(Sphecidae) Ammophila)]'' are known for hunting [http://en.wikipedia.org/wiki/Caterpillar caterpillars] that are destructive to crops.

Although its main ingredient is natural sugar (i.e., [http://en.wikipedia.org/wiki/Sucrose sucrose] (table sugar), glucose, and fructose), nectar is a brew of many chemicals. For example, the ''Nicotiana attenuata'', a tobacco plant native to the US state of [http://en.wikipedia.org/wiki/Utah Utah], uses several volatile [[aromas]] to attract pollinating birds and moths. The strongest such aroma is benzyl acetone, but the plant also adds bitter [http://en.wikipedia.org/wiki/Nicotine nicotine], which is less aromatic and therefore may not be detected by the bird until after taking a drink. [[Researchers]] speculate the [[purpose]] of this addition is to drive the bird away after only a sip, [[motivating]] it to visit other plants to fill its [[hunger]], and therefore maximizing the pollination efficiency gained by the plant for a minimum nectar output.[10] Neurotoxins such as [http://en.wikipedia.org/wiki/Aesculin aesculin] are present in some nectars such as that of the [http://en.wikipedia.org/wiki/California_Buckeye California Buckeye]. All twenty of the normal [http://en.wikipedia.org/wiki/Amino_acid amino acids] found in protein have been identified in various nectars, with alanine, arginine, serine, proline, glycine, isoleucine, threonine, and valine being the most prevalent.[http://en.wikipedia.org/wiki/Nectar]
