Butterfly House by Eve Bunting is a children's picture book about a girl and her grandfather who raise a caterpillar into a Painted Lady butterfly, creating a "butterfly house" (a decorated box) to help it through its life cycle. The story, illustrated by Greg Shed, follows the girl as she cares for the larva, releases the butterfly, and later, as an old woman, finds that butterflies return to her garden, believing they are descendants of the one she saved. It's a story about kindness, nature, and the life cycle, often used in science and literacy lessons.
