Immature Insects, Volumes 1 and 2, edited by Frederick W. Stehr, are excellent sources of information on the biology and ecology of insect families, making these indispensible textbooks. With abundant illustrations, descriptions, and keys, both volumes are also useful as field guides in identifying many common, economically important, or unusual species. Immature Insects is the only reference that extensively details information necessary to identify immature insects. These books explain the techniques for collecting, rearing, killing, preserving, storing, studying, and shipping insects. Well-illustrated keys are provided for all orders and families. Immature Insects, Volumes 1 and 2 can be used for an introductory class or as an identification guide for the larvae of all insects.
