                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               Incroyable, Incroyable ...  ce papillon est un véritable chef-d’œuvre de la nature ! Loin d’avoir eu les ailes découpées par de minuscules ciseaux, le Greta oto les a en réalité transparentes. Cette particularité lui vaut le surnom de “papillon de cristal” en espagnol et “ailes de verre” en anglais.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 Le procédé qui permet de créer ce petit miracle est complexe et intéresse particulièrement la communauté scientifique.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       De récentes études ont révélé qu’il pourrait permettre à terme de développer certaines technologies. Et notamment, un objet qui nous concerne dans notre vie de tous les jours : un écran sans reflet !                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   Qui aurait pu croire qu’un si petit insecte, d’Amérique centrale, pouvait faire autant ?
