Fig. 10.2. Traplining of two bumble bees in a flight arena (105 cm : : 75 cm) with six artificial flowers. The left panels show the arrangement of flowers (black squares), and the frequency of flight paths within it. The arrow on the right marks the location of the nest entrance to the arena. The width of the arrows corresponds to the frequency each trajectory was taken. For example, in the upper left panel, the arrow from the hive to the closest flower corresponds to 38 of a total of 40 foraging bouts. The right panels show how often each flower occupied a given sequential position within a foraging bout. Note that the right panels contains only the first six visits of each foraging bout, whereas the left panels contain the information from all flights. Because bees often revisited flowers they had already emptied, a foraging bout can have more than six visits.
