Data from: How to find home backwards? Locomotion and inter-leg coordination during rearward walking of Cataglyphis fortis desert ants

supplementary video V1 (backward walking)Shown is an ant in backward locomotion dragging a large food item. Note that the walking pattern is irregular, without any tripod coordination.supplementary video V2 (forward walking)Shown is an ant walking in tripod fashion during forward locomotion. Note that three legs are coupled and are swinging in unison, while the other three legs remain on the ground.supplementary video V3 (forward pulling)Ants prefer to walk in forward-faced orientation, as long as the shape and weight of a food item makes this possible. Shown here is an example of an ant that has a food item that is too light-weight for backward dragging and the ant pushes the item forwards towards its home nest.supplementary video V4 (backward tripod-like coordination)Shown is an ant in backward locomotion. Generally, a detailed analysis of the ants’ inter-leg coordination revealed an irregular locomotion during backward walking. However, in this video we find the tendency that the legs of one tripod group are swinging more or less simultaneously. This indicates that backward tripod coordination is per se possible.
