The stick insect's body is bright green. When they perch on a branch, they look no different from a dead branch.
Not only that, the body color of stick insects will change with the changes in the surrounding environment, sometimes green, sometimes brown, and sometimes yellow.
In addition, stick insects will change the brightness of their colors according to changes in external temperature. When the temperature drops, the color of the stick insect will darken; when the temperature rises, its color will lighten. It is with these tricks that stick insects have successfully deceived the eyes of their enemies and become a veritable "master of camouflage."
