Etymology: The adelgid is a tiny aphid-like insect, and its name rests on a Greek word that may never have existed. Scholars working in the Renaissance-era classical tradition coined the New Latin genus name "Adelges" for these pests, and "adelgid" simply adds the family suffix "-id" to it, the standard way zoologists name members of an insect family. The English term appeared only in 1928, so it is a modern scientific coinage rather than an ancient one. The genus name was built from a supposed ancient Greek verb, "adelgeîn," meaning "to suck." No ancient text records this verb, so it is best described as reconstructed rather than attested. It was probably a confusion with "amelgeîn," a real Greek verb meaning "to milk," or "to suck up moisture" and "to drink," which fits the insects' habit of feeding on tree sap. The word thus carries a faint echo of milking, though no ancient writer ever applied it to these creatures.
