sidering the actually imposed changes in leg length) that ants might run by as much faster on stilts as they ran slower on stumps (0.48 m/s, a value regularly observed in highly motivated normal ants and almost reached by the fastest ants on stilts). This procedure indeed yields a value that is not significantly different from the observed homing distances in ants on stilts (open box in Fig. 3, A; 14.25 m, IQR 0 3.35 m), thus confirming the consistency of our data with the step integrator hypothesis. The slower speeds of the ants walking on stilts further rule out the only alternative explanation of our homing distance data (Fig. 3A, solid boxes). In principle, a step integrator and a time-lapse integrator would both yield the same homing distances, even in ants with manipulated leg and stride lengths, if only the ants kept their stride frequencies constant E or in normal ants, walking speed—which in fact they almost do under nor- mal conditions ( 19 , 20 ) ^ . Constant stride frequen- cy would result in a change in walking speed in proportion to altered stride length and a resulting difference in homing distance during a set (out- bound) travel time. This assumption is evidently not correct, though, given the walking speeds of the experimental animals.
