  • Numerous non-flying arboreal vertebrates use controlled descent (either parachuting or gliding sensu stricto ) to avoid predation or to locate resources, and directional control during a jump or fall is thought to be an important stage in the evolution of flight. Here we show that workers of the neotropical ant Cephalotes atratus L. (Hymenoptera: Formicidae) use directed aerial descent to return to their home tree trunk with >80% success during a fall. Videotaped falls reveal that C. atratus… CONTINUE READING
