Over 250 million years, numerous insect species have developed camouflage to evade predators. When resting, color, shape and outline of the animal disrupt its form and merge with the background so that it is not recognizable anymore. Similar to camouflage is disguise, or mimetic camouflage, in which the entire insect looks like a leaf, a twig or dropping that predators overlook. An astonishing number of butterflies and moths have evolved this method of concealment. The Angle Shades owlet moth can hardly be detected when sitting among dead leaves.
