I've got a friend, Destin, who has a YouTube channel called Smarter Every Day, where he pokes around with his camera to get extremely intimate looks at small miracles in nature. In this one, about the secret life of baby butterflies, he learns that when it comes time for the caterpillar to turn itself into a butterfly, it doesn't spin a lot of silk and build itself a shelter (a pupa). I thought that what caterpillars do. But no ... take a look at what actually happens.
There's another mystery here that Destin has yet to ponder. (But he says he will. He's working on it for later this year.) We've read, and reported on this blog that when it's time for caterpillars to transform themselves, once they are safe inside the pupa, they melt.
