Innate turning preference of leaf-cutting ants in the absence of external orientation cues
Journal of Experimental Biology
Most ants use a combination of cues for orientation but how do ants find their way when all external cues are suppressed? Do they walk in a random way or are their movements spatially oriented? Here, we show for the first time that leaf-cutting ants (Acromyrmex lundii) have an innate preference for turning counter-clockwise (left) when external cues are precluded. We demonstrated this by allowing individual ants to run freely on the water surface of a newly developed treadmill. The surfacedoi:10.1242/jeb.177006 pmid:29880635 fatcat:k4acvddydbc57aqrliswuck5ry
