Final tiger swallowtail caterpillar of 2013 attaches!!!

This large brown tiger swallowtail caterpillar finally stopped munching on the tulip tree branches that were kept fresh in wet sand for five weeks and attached itself to a twig yesterday. Hoping it creates its chrysalis today! The chrysalis will overwinter on my unheated back porch and one of North America's largest butterflies should emerge in May 2014!
