Aphids have a special symbiotic relationship with ants. Some ant species “farm” aphids because they secrete a liquid called honeydew, which is very sugar-rich, and quite favored by ants as a food source. In return, ants herd aphids around the juiciest parts of plants and provide protection to them.
