Their Latin name Phasmatodea comes from the Ancient Greek ‘phasma’, meaning apparition, phantom or ghost. This referred to the fact that they resemble plants, while actually being animals.
Masters of disguise
Their patterns and colours camouflage them into their environment as sticks or leaves. If the wind is blowing they can sway their bodies to mimic leaves or sticks moving with the wind, so they remain hidden from predators.
Stick insects have a range of defences against predators including faking their death (remaining very still), releasing foul odours and releasing an entire limb to escape the grasp of a predator.
