Imagine a dark night...

... and you are walking through the Australian forest, and one of these giant prickly stick insects land on you, in your hair or on your shoulder and starts walking across you in search for some good leaves to eat. Would you like that? Amazing creatures, fascinating. One subspecies of this species even imitates lichens. We saw these at the Liberty Science Center, NJ, USA, where they mostly were hanging around upside down, not doing much in particular.
