Third in a series of nature picture books, the first two of which were Which Bird Is It? and What Animal Is It? This one, too, makes use of questions to stimulate the reader's interest, by posing an odd puzzling question to lead into the short informative text on types of butterflies. This acts as a sort of teaser, with the answer to each question given in the text below. The accompanying illustrations are colorful, neatly drawn, but lacking in detail, and with somewhat confusing labeling. Occasionally, there is no label at all. There's need for a good first butterfly book, so it is too bad that this hasn't more accurate basic facts. It leans too heavily on entertaining oddments.
