Aphid \A"phid\, n. (Zo["o]l.) One of the genus Aphis; an aphidian.

Douglas Harper's Etymology Dictionary

1884, anglicized from Modern Latin aphides, plural of aphis, coined by Linnaeus (1758), though where he got it and why he applied it to the plant louse are mysteries. The theory favored by OED as "least improbable" is that it derives from the Greek apheides "unsparing, lavishly bestowed," in reference either to the "prodigious rate of production" of the insects or their voracity. They also are known as ant-cows.


n. sapsucking pest insect of the superfamily ''Aphidoidea''; an aphidian.


n. any of various small plant-sucking insects


Aphids, also known as plant lice and in Britain and the Commonwealth as greenflies, blackflies, or whiteflies (not to be confused with " jumping plant lice" or true whiteflies), are small sap-sucking insects, and members of the superfamily Aphidoidea. Many species are green but other commonly occurring species may be white and wooly or black. Aphids are among the most destructive insect pests on cultivated plants in temperate regions. The damage they do to plants has made them enemies of farmers and gardeners the world over. From a zoological standpoint they are a highly successful group of organisms. Their success is due in part to the asexual reproductive capabilities of some species.

About 4,400 species are known, all included in the family Aphididae. Around 250 species are serious pests for agriculture and forestry as well as an annoyance for gardeners. They vary in length from .

Natural enemies include predatory ladybugs, hoverfly larvae, parasitic wasps, aphid midge larvae, crab spiders, lacewings, and entomopathogenic fungi such as Lecanicillium lecanii and the Entomophthorales.
