, butterfly wings are made of very thin layers of a hardened protein called chitin. (Your hair and nails are also made out of this protein.) On top of these chitin layers are thousands of tiny scales that serve several purposes, which may vary for different species of butterflies.lthough you can't see them, a system of miniscule veins runs through the wings and if the vein on the forewing gets broken, the butterfly will usually die [source: Opler ].
