Leaf-mimic katydid explained

There are many insects in the family Tettigoniidae (bush crickets or katydids) which are mimics of leaves.^[1]

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

• Pterochrozinae^[2]
• Phaneropterinae
• Pseudophyllinae

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