Fig 4. Foraging success.

Average data (mean ± s.e.) for the seven resident (black dots) and the seven newcomer (white dots) bees during all consecutive foraging bouts of the two experimental phases. (a) Mean number of different flowers visited per foraging bout; (b) number of revisits to the same flowers per foraging bout; (c) travel speed per foraging bout; (d) net energy intake rate per foraging bout. Grey arrows show the moment when newcomers were introduced in the array of flowers (bout 26). Additional foraging bouts by resident bees during the two-forager phase (> bout 50) are not shown.
