Honeybees flying repeatedly over the same trajectory link it to an associated visual stimulus such that on viewing the stimulus they perform a trajectory in the habitual direction. To test if trajectory length can also be linked to a visual stimulus, bees were trained to fly through a multi-comparmented maze. Bees flew through a multi-compartmented maze. In one compartment a short trajectory could be linked to a stripe pattern oriented at 45 ~ to the horizontal. In another compartment a longer trajectory could be linked to 135 ~ stripes. Bees made both associations: their trajectories were short when viewing 45 ~ stripes and longer when viewing 135 ~ stripes. 90 ~ stripes evoked trajectories of intermediate length.To test if distance and direction are linked independently to stripe orientation, a bee's trajectory was linked to 135 ~ stripes in one compartment and to 45 ~ stripes in another. These trajectories were the same length but differed in their horizontal direction by 60 ~ or by 120 ~ . 90 ~ stripes evoked trajectories of intermediate direction which were shorter than those elicited by either training pattern. Bees were also trained to generate one long and one short trajectory with directions 120 ~ apart. The trajectories elicited by 90 ~ stripes were then biased towards the direction of the long training vector. Length and direction are not treated separately. The rules for combining trajectories resemble those of vector averaging.
