The Uraba lugens or Gum leaf skeletoniser or Mad hatterpillar is a caterpillar that has a stack of hollow heads on top of its main head! This video is really short compared to my usual videos. Don't worry, I'm still making the same number of long videos but now you get these short videos in between!
