Figure 6. Female mate choice when there was a 24 hours delay between the demonstration and test phases (Experiment 4).

During the demonstration, females were allowed to watch Mated and Unmated males in the two peripheral vials. Mate choice was assessed either immediately (no delay, which triplicate the situation of Fig. 3 left bars) or 24 hours later (24 hours delay). Females avoided Mated over Unmated males immediately after the demonstration but not after a 24 hours delay when they showed an opposite preference (GLM, male type×treatment: Chi²₁ = 10.17, p = 0.0014). The horizontal dashed line corresponds to random mate choice.
