<p><b>(A)</b> Male forewings were dissected as shown in the panel. Measurements of the area (mm<sup>2</sup>) of the harp and mirror regions were obtained as indicated in magenta and blue, respectively. (B) Correlations between the harp size (magenta circle) or mirror size (blue circle) and whole body mass. The vertical axis shows the area (mm<sup>2</sup>) and the horizontal axis shows the cricket mass (mg). Both areas correlated significantly with the body mass. The correlation coefficient (r) and p values are presented in the graph.</p
