Ian writes, August 24, 2008, "Four-horned sphinx larva bit the webbing of my finger while I tried to move him to another birch cutting and drew blood. He has some big old jaws on him and very powerfull. I won't be picking him up for a while."

On August 28, Ian writes, "The Four-horned sphinx again. He wasn't quite as nippy today but he is 4 inches long!!!"
