In addition to the exciting main story of the book, the young reader learns interesting facts about butterflies: what funny names native butterflies have, how astonishingly fast, high, and far they can fly, that there are even wingless butterflies, and those that are unfazed by winter, as well as those that enjoy cheese or cocoa, those that like to feed on dung, or those that never eat anything. Furthermore, the story weaves in the role that well-known medicinal plants can play in the home pharmacy. The entertaining quiz at the end of the book allows young readers to check what interesting facts they have remembered.
