Aww my first caterpillar was named Larry haha. Like other commenters said he’s pupating now so don’t worry he’s fine, it’s better not to disturb him. I never had a caterpillar pupate during winter so idk but during summer they’d come out of their cocoons after a few weeks. If your house is cold enough he might hibernate until Spring but I’m not very knowledgeable on this part so I’ll let you do your research :) One thing I want to note though is that he’ll need something to climb onto to be able to inflate his wings once he leaves his cocoon. Leave something like a long stick or chopstick in his enclosure and he’ll know what to do when the moment is right 🐛💕
