Tiny soft-bodied insects that feed on plant sap, often found in large colonies on leaves and stems, sometimes called plant lice.
From Greek 'aphides,' possibly related to 'aphanés' meaning 'obscure' or 'invisible' because they're so small. The term was formalized in scientific nomenclature during the 1600s.
Aphids are farming insects—some ants literally herd and milk aphids for their sweet secretions, which means insects discovered agriculture before humans did!
