The authors maintain the tradition of clarity and conciseness set by earlier editions, and the text is illustrated profusely with specially commissioned hand-drawn figures. The illustrations and the informative text aim to encourage the scientific study of insects, either as a vocation or as a hobby. The book is intended as the principal text for students studying entomology, as well as a reference text for undergraduate and graduate courses in fields of ecology, agriculture, fisheries and forestry, palaeontology, zoology, and medical and veterinary science.
