These desert ants are on a mission: find food and bring it home, no matter the size and shape. But new research suggests ants walking backward are as good at navigating to their destination as forward walking ends. This means they must somehow measure the length of each stride they take or use other tools to keep track of their location. The researchers say when ants find something too large to be lifted and carried forward they drag it backwards. So the researchers put the ants reversing navigation skills to the test. They painted a white grid onto the desert floor and released an ant with a large food crumb and it began its backward trek towards its home. During normal forward homing the ant goes straight to its fictive home indicated with the red dot. During backward homing ants frequently interrupted reading and performed foodless search loops probably to gain further orientation cues. The research published in the journal of experimental biology use high-speed camera recordings. It found that backward traveling ants showed surprising flexibility with intellect coordination, in comparison with the forward walking ones.
