Outline of Final Research Achievements

Male of the light blue dragonfly Orthetrum albistylum changes the body color from light brown to light blue in the maturation process. We found that this color transition is attributed to the changes of the wax-based surface nanostructures, which coincides with strong UV reflection and water repellency. We also identified seven components of UV reflecting wax, and confirmed that the synthesized wax also had UV reflection and water repellency abilities.
