Ants, unlike bees, do not use maps, but adhere to learnt routes in tussock rich desert habitats of Central Australia. A team of Swiss researchers highlight these findings in the Australian endemic ant Melophorus bagoti. Melophorus are solitary foragers, and each ant establishes idiosyncratic paths in their cluttered environment and adheres to them. What’s interesting is that, the foodbound and nestbound routes are different and are not mere 180 degree reversals of each other. When an ant heading home is displaced, she searches till she finds the familiar homebound route and then ‘channels in’ to reach the nest. However in this period if the ant crosses the foodward path, they continue to search as if lost, thus providing evidence of ‘one-way route navigation’.
