Fig. 3. Hovering times of bees in the experiment illustrated in Fig. 2A. (A,B) Total hovering time at the feeder and nest ends. Total hovering time averaged across bees is plotted against trial number. (C,D) Relative hovering times at the feeder and nest ends spent in front of positive (+ve) or negative (-ve) patterns. Values are means ± S.E.M. (N=8).
