Butterfly or Moth

Yesterday morning I took the caterpillar out and clean the cage. I replaced him with fresh leaves and 2 sticks. He hasn't been moving much and I had just read that that sometimes mean that they are ready to go into the pupa stage. Then yesterday late afternoon he was hangin upside down on one of the sticks and there was a web like substance. But he didn't stay there. He moved closer to the bottom of the container and he started making a cocoon between the side a leaf the bottom and a stick. By last night you could still see him but he was completely covered with this silk/web stuff. Well this morning we can't see inside the cocoon. I'm also guessing that since it is a cocoon that he will turn into a moth and NOT a butterfly. Zachary has loved watching this whole process, but he is already getting sad about having to let his pet go once it turns into whatever it turns into. Will keep you posted!
