Abstract
This study describes the structural coloration of the butterfly Vanessa Atalanta wings and shows how the atomic force microscopy (AFM) can be applied to the study of wings morphology and wings surface behavior under the temperature. The role of the wings morphology in colors was investigated. Different colors of wings have different topology and can be identified by them. AFM in semi-contact mode was used to study the wings surface. The wing surface area, which is close to the butterfly body, has shiny brown color and the peak of surface roughness is about 600 nm. The changing of morphology at different temperatures is shown.

Atomic force microscopy, diffraction, morphology, natural nanostructure, reflection, structural color, temperature influence
There are optical scales alone which provide a metallic lustre of butterfly wings
The light reflected from the wings undergoes repeated reflections
Summary
Atomic force microscopy, diffraction, morphology, natural nanostructure, reflection, structural color, temperature influence. There are optical scales alone which provide a metallic lustre of butterfly wings. The scales protect wings, improve their aerodynamics properties, and control a variation of temperature.
