3. A Katydid camouflaging into its surroundings (Amazon Rain forest)
Insects in the family Tettigoniidae are commonly called katydids or bush-crickets. There are more than 6,400 species. Part of the suborder Ensifera, it is the only family in the superfamily Tettigonioidea. They are also known as long-horned grasshoppers, although they are more closely related to crickets and weta than to any type of grasshopper. Many tettigoniids exhibit mimicry and camouflage, commonly with shapes and colors similar to leaves.
