This is a photo, of five, beautiful, Moth Cocoons, resting on some paper, inside my house..... 2- Polyphemus Moth Cocoons. 2- Promethea Moth Cocoons. and 1- Cecropia Moth Cocoon. INFORMATION: Next week, I'm going to cut open the Cecropia Moth Cocoon, and carefully remove it's Pupa. Then I'm going to take a magnifying glass, and carefully study the inside and outside of it's Cocoon. I'm also going to study it's Pupa, with a magnifying glass. After I finish studying the Cecropia Moth's Cocoon, and Pupa, I will sketch (draw ) both the Cocoon and Pupa, with an ink pen. This is another way to learn about a Moth's Cocoon and Pupa, is to sketch (draw ) them both, with an ink pen. I will put both sketches, inside my - Butterfly and Moth - notebook. Then I will put the Pupa inside my terrarium, and wait for it to eclose.
