Leaf-mimic katydid

There are many insects in the family Tettigoniidae (bush crickets or katydids) which are mimics of leaves. At a distance the katydid is an example of crypsis evading detection by blending into its background; up close the katydid mimics a leaf.

This type of camouflage occurs in several subfamilies, among others including:

Other unrelated insects adopting a similar camouflage strategy include the leaf insects.
