Etymology
The word adelgid comes from the scientific name Adelges, used for a group of very small insects that feed on the sap of conifer trees. A helpful way to remember it is to think of adelgids like tiny 'aphids' that cause 'galls' or bumps on 'pines' and 'spruces', which is why the word means a small tree pest.
