Correlation between potential pigment accumulation and visible reflectivity. We considered the mean RGB values under the RCP filter to be inversely proportional to the amount of pigment in the elytra. Beetles with lower reflectance in the RCP filter potentially accumulate more pigments, yet their overall appearance (no filter) remains diverse thanks to the chiral nanostructures. Beetles are not scaled proportionally to their original size. Error bars indicate mean and standard deviation of the two variables per species. Trend line calculated based on the estimates of the PGLS models.
