I took this photo of a young walking stick the other day. It is the first time I ever saw one actually molting. It was on a rose bush in our garden here in Northwest Arkansas. I suppose it had to hang there exposed until its new exoskeleton hardened. It is obviously a good deal larger than its old skin that is attached to the rose leaf.
Thank you for sending us your contribution. Like other arthropods, Walkingsticks cannot grow until their hard exoskeleton is shed, which allows room for expansion.
