Butterflies can be lured into capture by decoys
Butterflies can be lured into capture by decoys. Naturalists cement the wings of a dead butterfly to a head and body that has been sketched on cardboard. The object is then cut out and covered with cellophane to protect it. When suspended from a twig by a thread it will turn in a lifelike manner whenever a breeze strikes it. While real butterflies will not stop or touch it, they will hesitate or flutter around momentarily, so that the naturalist has opportunity to net them. (Lou Nicholes - Missionary/Author).
