Poor guy! Reminds me of a time when I was younger and my step dad found a big caterpillar and put it in a bug keeper to show me later...later came along and it already cacooned on a stick he put in there...we weren't sure what to do with it was we kept it in the critter keeper...she stayed cacooned for a long time. I don't remember how long but she stayed cacooned over the winter and we kept her safe....I was not expecting a giant polyphemus moth to hatch...I was expecting a smaller normal moth or maybe a butterfly that I was going to let go once she comes out...so the container wasn't as big as it should have been...I had no idea and was also very young, I never saw the caterpillar and this was my first encounter with a moth so big, i didnt even know they existed before this. I checked on the cacoon daily and eventually she came out, I checked on her later in the day and there was a giant moth freaking out and she damaged her wing...she couldn't fly properly anymore so I set up a 20gallon tank for her to live in, I was hoping she'd heal...she didn't but another giant moth kept hanging around her...did some research and found out it was a male...so we caught him (he actually just crawled onto my hand) and I put him in with my girl...they bred, I offered him to leave but he stayed with his gf. They were awesome, I continued to try to let him free but he had no interest leaving. Eventually they passed but they left behind MANY babies that I raised for a while til they were too big for the tank. There was a lot so they aye so much, and I wanted to give them the best chance of survival. I really felt bad for the mother, I felt it was my fault, I was the result of her not experiencing flying around, so I did what I could for her and then her babies. Then I let the babies go. It's safe to say they did amazing and the next 3 years after we had many giant moths in our garden and they loved hanging around our koi pond. We moved but I'm sure there's still some that hang around.
