Explanation

An aphid is a bug that's considered a pest by many gardeners. Aphids like to eat a variety of plants, including roses, lettuce, peaches, and grapes. Aphids feed by sucking sap or liquid from a plant, and they can be quite destructive to a farmer's crop or a gardener's flower bed, because they reproduce quickly and efficiently. Several kinds of birds and spiders prey on aphids, and farmers use both chemical and biological insecticides to control them. The word aphid comes from the Modern Latin aphis, from 1758, although its origin isn't known.
