Fig. 4. Trajectories of homing ants following a sideways displacement. Ants travelled through a route-mark corridor (array of black circles) from nest N to a feeder F and were displaced from the feeder 1.5 m (N=21), 3 m (N=20), 6 m (N=18) and 10 m (N=21) from the feeder. (A) All trajectories of ants displaced sideways. (B) Example paths of ants at each displaced distance that had zero turns (black), one turn (blue), no loops (green) and one loop (red) are shown. Grid size is 1 m².
