Adelgidae

Part of speech: noun

Definitions

1. A family of small, piercing insects primarily found on various types of plants, known commonly as whiteflies
2. They are characterized by their waxy bodies and the ability to produce honeydew
3. This group of insects can cause significant damage to crops and ornamental plants through their feeding habits

Etymology: The name was coined in the 19th century for a scientific genus, not an ancient word. The type genus, "Adelges," was named by the French naturalist Vallot in 1829, and the family name adds the standard zoological ending "-idae" to it. The genus name is generally taken to come from the Greek "adēlos," meaning "unseen" or "obscure," probably a reference to how inconspicuous these insects are, often hidden under woolly wax coverings. A correction to the meaning you provided: adelgids are not whiteflies. Whiteflies belong to a separate family, Aleyrodidae. Adelgids are sap-feeding insects that live almost entirely on conifers such as spruces, firs, and larches, and some species are notable pests of those trees. The family name refers to these insects specifically.

Synonyms: adelgid, pine aphid
