Stick insects look like twigs of sticks and are practically invisible from almost anywhere. They are herbivorous and spend their life on trees where they also get their food. Their brown, thin-shaped bodies make them invisible to their enemies. They can also be green in colour. They tend to freeze when threatened and may even sway like a branch blowing in the wind. Stick insects display structural, physiological and behavioural adaptation that allows them a better chance of survival in their particular environment.
Why are stick insects so successful at camouflage?
