Fig. 6. Responses of female M. septendecim to playbacks of artificial, pure tone calls and portions of calls against artificial background choruses of different intensities. Females were scored as responding positively if they produced one or more wing flick signals in response to a playback. Data are presented as proportion of positive responses for specific call and background condition given the total number of trials with those experimental conditions. At all background intensities, whole calls (squares) were more likely to elicit responses than either main portion only (circles) or slur portion only (triangles). At higher background intensities, the effectiveness of whole calls was reduced (Kruskal-Wallis One Way ANOVA z = 420, p ≤ 0.001), as was the effectiveness of main portion only (Kruskal-Wallis One Way ANOVA z = 64, p ≤ 0.001), while the effectiveness of slurs alone was increased (Kruskal-Wallis One Way ANOVA z = 44, p ≤ 0.001).
