Communication by Tandem Running in the Ant GenusCardiocondyla

摘要

During field work in Puerto Rico in June,196o, the author hadthe opportunity to study a hitherto little known form of communicationamong worker ants. This behavior, which for convenience mightbe called tandem running, involves the movement outward from thenest of closely coupled tandem pairs, and it apparently functions asa substitute or trail-laying to recruit fellow workers to food sources.On Puerto Rico, tandem running was studied more fully in the speciesCardiocondyla venustulaWheeler but was also observed in a secondmember of the genus,C. emeryi Forel.
