Unlike flapping birds and insects, bats possess membrane wings that are more similar to many gliding mammals. The vast majority of the wing is composed of a thin compliant skin membrane stretched between the limbs, hand, and body.he musculoskeletal system of bat wings affords the potential to adjust membrane deformations in several ways. The boundary of the membrane is set by the articulated wing skeleton, which dictates membrane position and orientation.
, 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 ]. So while death isn't necessarily imminent for a butterfly if you happen to touch its wings, the odds aren't on its side either.
