Quote from Reese in Butterflies
Reese: Did you know the Latin name for this little guy is Danaus plexippus, and that he actually crawls out of his own skin to pupate? Then the outer layer hardens into the chrysalis. That's Greek for "golden." And once they turn into butterflies, they can migrate up to 2,000 miles. Pretty awesome, huh? Oh, got to feed them some more milkweed.
