Fig. 2. Trajectories of homebound ants in (A) an unfamiliar test field and (B) the
familiar training field. Each line represents the path of an ant. (A)
Trajectories of FvRm+ (N=24), FvRm (N=17) and ZvRm+
(N=15) from release point R towards the fictive nest N*. (B)
Trajectories of FvRm+ (N=20), FvRm (N=20) and ZvRm+
(N=21) from the feeder F to the nest N. Route-marks for homing ants
are shown as black circles. In FvRm condition, the grey circles
indicate the location of the route-marks that were removed during test
conditions. Grid size is 1 m2.
