This is time lapse video of a black swallowtail butterfly emerging from its chrysalis and letting its wings expand. When a butterfly comes out, it has to hang upside down to let its wings fill up with fluid before it can fly. This takes a long time so it's hard to see with the naked eye. Speeding up the video let's you see it. There's a slower version of this, and other videos like it, at WildlifeTheater.com. I hope you enjoy it.
