Saunders Case Moth Caterpillar (Metura Elongatus) Cocoon Attached To A Tree Trunk. The Case Moth Caterpillar Builds Its Cocoon Sack From The Head End. So, As It Grows Bigger, It Has To Attach More, And Larger Twigs. These Cases Are Very Strong. The Twigs Themselves Are Incorporated Into The Silk By The Caterpillar Cutting A Slit On The Inside, Temporarily Attaching A Twig To The Outside Beforehand
