There is no doubt that these creatures (stick insect also known as walking stick) are excellent mimic, copying exactly the twig it perches on and resembling the natural twigs of the plant it presently resides in to protect them from predators.
I concluded however that it has more to its arsenal than just mimicking a twig. This fantastic visitor of my azotea potted garden showed me how to dance!
Well, at first that was my impression. Rhythmic forward and backward rocking movements that can easily be matched with the latest dance tunes!
Further search however led me to an explanation of these movements. It says that this is actually another form of mimicry– mimicking the swaying of the branch while a light gentle wind is blowing.
