a, Color contrast (just noticeable difference, JND) between forth-instar orchid mantises and various flowers as perceived by the butterfly Pieris rapae, or the bird Cyanistes caeruleus and Pavo cristatus. The gray box plot represents the contrast between the WT orchid mantis (n = 10) and the flowers (J. sambac: n = 10, C. sinensis: n = 5, G. jasminoides: n = 10), while the purple box plot represents the contrast between the Redboy-RNAi orchid mantis (n = 9) and flowers. Color contrast values ≤ 3 indicate low discriminability of the colours for a given visual system (dashed line = 3). solid box plot: achromatic contrast, hollow box plot: chromatic contrast, and also for subsequent representation. b, Examination of color contrast between second-instar WT (black box plot, n = 10) or Redboy-RNAi (red box plot, n = 10) orchid mantises and various flowers from perspectives of the butterfly P. rapae and bird C. caeruleus. These data were also illustrated by spectral reflectance (mean ± S.E.). c, Color contrast between the flower model (n = 10) and real flowers from the perspective of the butterfly P. rapae or the peacock P. cristatus. Box plots depict the median, upper and lower quartiles, and maxima and minima; dots indicate outliers. *P < 0.05; **P < 0.01; ***P < 0.001, each test have been repeated for more than 3 times. Source data are provided in Source Data Extended Data Fig. 5. We chose one of Kruskal‒Wallis test, One-way ANOVA and Welch’s ANOVA according to the data normality and variance heterogeneity in statistics, and the results are provided in Supplementary Table 3.
