This field guide was created by 2nd graders in Springfield, Massachusetts. It was part of a two-month Learning Expedition that included field observation and collection, classroom experimentation and research, reading from books and websites, and work with a local entomologist. Students became experts in the insects local to Western Massachusetts, and then began working with a partner on a specific insect. Each entry in the field guide contains scientific illustrations of the pair's insect, a life cycle of the insect, and detailed written descriptions.
