Visual spatial memory in desert ants,Cataglyphis bicolor (Hymenoptera: Formicidae)

Summary

For navigation, desert ants apply piloting and dead-reckoning strategies based on terrestrial and celestial visual cues, respectively. Visual spatial memories, rather than general concepts derived from landmark constellations, are most probably used to define points on earth by nearby landmarks. The visual field of a specialized dorsal part of the ant's retina is mapped on to the celestial sphere to consider the possibility that similar mechanisms are used to define directions on earth by exploiting skylight patterns present at infinity.

What the concept of visual spatial memory would imply in that respect is that the ant would have to be able to rotate a stored image in its head (by 15°/h about the north-south axis of the celestial sphere; the latter is not shown in figure 2).Google Scholar
