my little sister Lillie has been caring for about 4 or 5 cocoons these past few weeks, one of which hatched today. its a swallow tail, and still very fragile. but so beautiful. :) i asked Lillie what it's name should be, (we can't not name every living thing we own, even if only for a little while. :P) and she said, "Well, the last one was named Rainbow..........so this one should be, Fred." we were having trouble getting Fred to get out of his little shelter, so he upgraded to Stubborn Fred.
