This one is a 3.5 for me, and any educator worth his/her/their salt will marvel at the colors used in the illustrations of the beautiful monarch butterfly. There's probably nothing more pleasing to the eye than seeing one of those colorful creatures lighting on a blossom or fluttering through the air. In this book, Gail Gibbons introduces youngsters to these butterflies, beginning with a small egg laid on a milkweed plant, and then following it through the various steps of its life cycle as a larva, caterpillar, chrysalis, and finally, a butterfly. She even discusses how some butterflies, those born in spring and the first part of summer, have very short lives, while others, born in the middle of the summer, head to warmer climates once cool temperatures arrive, staying there during the winter, and then flying back home once it warms up again. The book also contains instructions for how to raise a monarch butterfly, but anyone interested in doing so needs to make sure that the area where they are released has the kinds of plant food they prefer. This is an updated version of the original book published in 1989, proving once again that Gail Gibbons is the Grande Dame of life science and topics related to nature. This book, as with her others, is perfect for an elementary science classroom library and a must-have for anyone planning a lesson about butterflies or the life cycle.
