Fleas are some of the world's peskiest insects! This book's easy-to-read text and larger-than-life color photos bring the flea's world to life, introducing readers to a flea's diet, habitat, enemies, and methods of defense. Diagrams help readers investigate the concept of metamorphosis and identify body parts, from the flea's sharp mouthparts to its long hind legs. The digestive, respiratory, and circulatory systems are also described. A step-by-step approach to scientific classification helps place fleas within the order Siphonaptera. Readers are also encouraged to consider how fleas impact our daily lives, from pet care to bubonic plague. From cat fleas to rat fleas, young entomologists will enjoy uncovering the lives of these persistent creatures. Informative sidebars and Bug Bytes aim to peak readers' interest, while bolded glossary terms, phonetic spellings, and an index enhance readability.
