This text uses a taxonomic approach to introduce students to the science of entomology. Extensive use of identification keys acquaints students with all the families of insects in the United States and Canada and provides means for students to identify 95% or more of the insects found occurring in North America.
Donald Joyce Borror was a professor of entomology and zoology at Ohio State University. He founded the Borror Laboratory of Bioacoustics at the university, which houses one of the largest collections of recorded animal sounds in the world - it has more than 30,000 recordings of over 1400 species of animals.
As an entomologist and naturalist, he is known best as an expert on the order Odonata (dragonflies & damselflies), and for his book An Introduction to the Study of Insects.
I still use this book and keep it close by. The brief descriptions of the orders, families etc... are well written and usually a great starting point when identifying an insect.
