Tandem running

From Wikipedia, the free encyclopedia

Tandem running is a method of recruitment used by some species of ants, such as Temnothorax albipennis, to lead nestmates to food. It is dissimilar to other recruitment strategies used by social insects such as pheromone trails, in that ants using tandem running can only recruit one worker at a time. During a tandem run the worker leads the recruit, who maintains contact with the leader using her antennae. Some researchers have argued that this is an example of teaching in insects.^[1]
