In order to understand how Formica lugubris foragers orient in the vegetation, we used a simple three dimensional foraging system set-up in controlled laboratory conditions. The system was designed to investigate the respective role of chemical visual (directional light) and kinaesthetic cues both on the vertical axis and the horizontal plane. The results indicate that on the vertical axis, ants are able to utilize simultaneously various types of directional information e.g. chemical cues and directional light, with a preference for the latter in case of conflicting information. On the horizontal plane, the orientation was found to be essentially based on external references. Amongst the latter, chemical cues have been shown to be highly implicated and seem to have a greater reliability than any other orientating information available. However, when the scent trail is removed, ants are still able to relocate the food source by using the direction of the light rays. In addition, in spite of our methodological precautions, unidentified visual landmarks were unexpectedly found to intervene as auxiliary cues in the orientation on the horizontal plane.
