Figure 1. Summary of all flower choices made by foragers in the initial and reversal phase of experiment 2.

Choices are broken down into the colony mean (±1 S.E.) numbers of blue and yellow landings (panels A and B) and approaches (panels B and D) made during consecutive bins of 10 flower choices (n = 6 colonies). The flower choices begin with the first time the bee fed from a rewarding flower (yellow in the initial and blue in reversal phase).
