Fig. 4. Results of Experiment 2. Bees were trained and tested in an axially striped tunnel. (A) Bees tested without the landmark generally flew from one tunnel end to the other. (B-D) Bees tested with the landmark at the training site (B), shifted to unit 14 (C) and shifted to unit 4 (D), all made first turns near the landmark then tended to break visual contact on second turns (and often flew back to the entrance).
