Fig 1. Influence of male size and ‘female choice/male competition’ on courtship arousal threshold times.

(A). Single matings. (B). ‘Choice/competition’ assays where the second male was constrained behind a barrier. (C). ‘Choice/competition’ assays without any barriers. Values above bars are percentage of successful copulations (successful copulations/trials). P-values from Mann-Whitney-Wilcoxon’s test. SE. Standard Error. ^{a, b}. Time differences between ^a and ^b are due to differences in recuperation times after anesthesia (see method for details).
