The Visual Orientation of Desert Ants, Cataglyphis bicolor, by Means of Terrestrial Cues

Abstract

When in desert areas Cataglyphis ants are displaced from the nest entrance to any point more than 2 m apart, nearly all ants search around at random. Therefore a method is described to train the ants to a feeding place by simultaneously extinguishing all astromenotactical information about the azimuth of that place. Then the storage and use of information about terrestrial cues can be measured unambiguously. During a set of one foraging and one return run the ants receive information about a “route”, extending from the nest entrance to the feeding place and characterized by a specific constellation of tiny terrestrial cues. By offering artificial cues (black, vertically arranged two-dimensional screens) the significance of this route for reorientation can be markedly enhanced. A method is developed to quantify this effect of artificial horizon landmarks. In this way pattern recognition problems can be studied.
