Abstract
There are two theories about how honeybees estimate the distance to food sources. One theory proposes that distance flown is estimated in terms of energy consumption . The other suggests that the cue is visual, and is derived from the extent to which the image of the world has moved on the eye during the trip. Here the two theories are tested by observing dances of bees that have flown through a short, narrow tunnel to collect a food reward. The results show that the honeybee's “odometer” is visually driven. They also provide a calibration of the dance and the odometer in visual terms.

- The texture was a random black-and-white Julesz pattern of pixel size 1 cm by 1 cm.

- The feeder's position in the tunnel was altered by moving it in small steps over a period of 2 hours. After reaching the final position a further period of 2 hours was allowed before dances were filmed.
- The stripes were black and white and had a period of 8 cm.
- The distances were determined using an accurate digital map of the university campus (see map at Science Online www.sciencemag.org/feature/data/1046508.shl). Only one distance was tested at any given time.
- To prevent undesirable intercolony interactions we ran the outdoor flight experiments with the two hives in sequence not concurrently. No colony-specific or route-specific differences were apparent.

- Waggle dances were video-filmed at 25 frames per second and were later played back for frame-by-frame analysis. The duration of each waggle phase was measured in terms of the number of frames over which it occurred.

- Further work is necessary to ascertain the precise conditions under which image motion for odometry is assessed by the ventral [see (3)] or lateral [see (6)] fields of view.
