Abstract: After spatial conditioning to two differently coloured cues, Myrmica sabuleti Meinert, 1861 workers correctly negotiated a maze provided with the two coloured markers, both from the entrance to the exit and in the reverse direction. When the two markers were replaced by differently coloured ones, the ants failed to negotiate the maze. This suggests that, in nature, these ants can find their way using a few memorised landmarks rather than by learning entire trajectories. This supports a combined "snapshot" and "sketchmap" model.
