Mapping the navigational knowledge of Myrmecia croslandi ants. (a) Example homing paths of full-vector (red) and zero-vector (blue) ants from three nests (circles: black, yellow and green) Foragers from each nest were caught at the base of their favourite tree (stars: black, yellow and green) and were transferred in the dark to one of eight randomly selected release stations (open circles) at 10 m distance from the nest. Full-vector ants (red paths) were tracked until they arrived close to the nest and were captured and re-released as zero-vector ants (blue paths) at a release station opposite to the first one. Summary of paths of (b) full-vector (red) and (c) zero-vector ants (blue) from four nests. Paths are rotated to align the nest (black circle) and release location (grey circle).
