Stick insect (walking stick)

Vegetation, shrubs, trees, and gardens, especially in warm temperate or tropical regions. It is shown resting on a wall, where stick insects may wander or seek shelter.

Herbivorous, feeding mainly at night on leaves from trees, shrubs, and vines. Typical foods include bramble, rose, eucalyptus, guava, or other local foliage.

Usually slow-moving and nocturnal, relying on extreme camouflage and remaining motionless when threatened; some sway like a twig in wind. Adults reproduce sexually or, in some species, by parthenogenesis, and females drop or deposit eggs individually.

Generally harmless to people and do not bite or sting. They contribute to plant-based food webs and nutrient cycling, though abundant populations can occasionally damage ornamental or crop foliage.
