Answer 1

The family of insects called Phasmatodea (or Phasmida), also known as Stick Insects, Walking Sticks, or Stick Bugs. There are many types of stick insect found in warm climates around the world. They range in size from a mere inch (2-3cm) to over a foot (30cm+) in length. They are usually nocturnal- more so as they mature.

Stick insects are so-called because of their effective camouflage; they look like twigs and leaves! Many stick insects can gradually change colour with their environment to maintain this defence. Some have been noted to employ a rocking motion that is thought to mimic the swaying of foliage in the breeze, though they usually tend to hide from potential threats by remaining very still for prolonged periods.

Some stick insects produce noxious compounds which can dissuade predators with strong smells or irritation of the eyes and nose. Some even reveal bright colours in order to appear threatening to a potential predator. Another simple defence is just to drop from their perch and attempt to remain hidden once fallen.
