Over the recent decades, the bright colors seen on the wings of butterflies are widely evaluated frequently due to the cause of nano-structures and are not supported by preferable pigments or any other dyes. This nature of bright and shiny appearance of various butterflies are caused by so-called ‘structural features of various response of colours’ which are originating from the smart combination of nano- and microstructures. For the discovery of the physical origin of these structural colors, the color-causing nano-structures are integrated into a complex structure of scales, which have densely covers the wings of butterflies. A research team has recently discussed about the structural analysis of the ridges of the cover scales in the species of butterflies and its height and distance from different families and its subsequent analysis reveals a linear scaling law [ 1 ]. Peter Kӧchling et al., have further reported that the color of the butterfly wings serves for several purposes with...
