An ant colony has memories that its individual members don’t have - Big Think
A red wood ant colony remembers its trail system leading to the same trees, year after year, although no single ant does. The Finnish myrmecologist Rainer Rosengren showed that when the ants emerge in the spring, an older ant goes out with a young one along the older ant's habitual trail. The older ant dies and the younger ant adopts that trail as its own, thus leading the colony to remember, or reproduce, the previous year's trails.
