Fig. 10. Results of Experiment 5. Bees were trained at unit 21 with a landmark, and
(A) tested without the landmark, or (B) with the landmark at the training
site, searched in accord with odometry and landmark cues, respectively. (C)
Bees trained without a landmark and tested without a landmark also showed no
signs of the anomalous behaviour observed in Experiment 4. Note the different
y-axis scales in A,C and B. For an explanation of figure layout and
symbols, see Fig. 2.
