Technically, this is a counting book, but it's a vibrant, detailed offering. Beginning with zero (a deprived penguin, in Antarctica, that will likely never have the opportunity to see a butterfly) and progressing up to 25, each page asks readers to count ever-increasing numbers of moths and butterflies. Eye-catching, realistic colored-pencil illustrations emphasizing unique colors and markings align with pithy text describing interesting life-cycle facts and tidbits of trivia, such as "The color and design on the top size of butterfly wings is almost always completely different than the underside" and "The word for butterfly poop is 'frass.'" Each entry also provides the word for butterfly in a different language, including sign language. Young readers will likely enjoy counting the crisp, vivid drawings as well as attempting to pronounce the foreign words, such as borboleta, pulelehua, and rama-rama, among others, while older readres might appreciate the lively commentary. This is an attractive addition to counting books and will likely resonate with fans of Elisa Kleven's Glasswings (2013).
