Idalia: Butterfly Child

When the husband of a childless couple brings home a butterfly cocoon from the forest, they place it the warmest part of the house. The next morning the couple finds a baby girl with lilac eyes in the basket where they had placed the cocoon. Realizing that the girl is a Dryad baby they are determined to keep her out of the forest lest she touch the enchanted plant from which she came and return to her real form as a butterfly.
