Boxplots showing differences between species for the following parameters: dominant frequency, fundamental frequency, first and second frequency components above fundamental frequency, third frequency quartile and mean wingbeat frequency (statistical tests are reported in the main text). Different letters above boxplots indicate statistically significant differences between species based on Tukey’s HSD test (for exact values see Tables 1, 2, 3, 4, 5 and 6 in Additional file 2). Open circles represent outliers
