  • Title: Bi-directional route learning in wood ants.
    Author: Graham P, Collett TS.
    Journal: J Exp Biol; 2006 Sep; 209(Pt 18):3677-84. PubMed ID: 16943507.
    Abstract:
    Some ants and bees readily learn visually guided routes between their nests and feeding sites. They can learn the appearance of visual landmarks for the food-bound or homeward segment of the route when these landmarks are only present during that particular segment of their round trip. We show here that wood ants can also acquire landmark information for guiding their homeward path while running their food-bound path, and that this information may be picked up, when ants briefly reverse direction and retrace their steps for a short distance. These short periods of looking back tend to occur early in route acquisition and are more frequent on homeward than on food-bound segments.
