Dudley is a worm, an ugly worm, whom children tease and taunt.  Feeling like an outcast, Dudley meanders along in life, dreaming of a beautiful butterfly girl he saw.  Wanting to run away from home in shame, Dudley is convinced to stay, build himself a home, and wait.  He does, and he is transformed into a beautiful boy butterfly.  He and girl butterfly become friends and get married and live happily ever after.  Simple story.  There are a few more embellishments to the story to make it interesting than just what I’ve explained.  However, the story is sweet and is a perfect complement for a unit of the life cycle of insects.  The illustrations are amazing and are what make this book a treasure.  This story, though simple, is explained in words and concepts that kids understand.  Every school library should have a copy.
