Students of entomology at every level need to be able to identify and classify the insects they study. How to Know the Insects has helped generations of readers learn to do just that. The key to insect ordersthe largest section of the bookuses both written text and myriad illustrations to provide identification details down to the family level as well as for common species of each family. In addition, Bland and Jaques provide accounts of insect natural history, the basic biology of each order and of most families, and extensive material in finding, collecting, and preserving insects. The handbook serves as a valuable learning tool or reference for undergraduate and graduate students of entomology, science educators, insect collectors, and anyone interested in the diversity of insects.
