I knew what it was when I saw it.
A friend had one on his plant.
I guess it's a catapillar, the ones making those small holes on your leafs, and then they make a cocoon and the going into metamorphosis.
I wouldn't know how to get rid of them, but I think you can just better unwrap it and just take it out.(and kill it), cause I bet it's just at the buds, all these leaves folded. clean it up abit and see if it recovers, I think it will. And bett check for more if I were you. good luck
