Something I would like to know

I just heard a story on NPR about how moths can retain memories of things that happened to them when they were a caterpillar. That is mildly interesting, but here is what I found intriguing: the researcher mentioned that caterpillars become bug soup in their cocoons. She said that they basically liquefy themselves and then turn into a moth. I had never thought about how that worked before, but now I want to know more. Unfortunately, I can't find any details. When I try to Google it, I get lots of kid sites and gardening sites.

Maybe I will try Wikipedia later.
