Fig. 7. Illustration of the three competing directional cues for ants displaced sideways to R. Route cues direct the ants to move laterally towards the familiar route; distant cue direct the ants towards the nest, whereas the ants' path integrator, relying on the sky compass, directs the ant to the fictive nest N*. Information from route cues, distant cues and the path integrator are in conflict in full-vector ants. Information from route cues and distant cues are in conflict in zero-vector ants.
