I collect virtually every cicada book I can get my hands on, including books written for children. They often contain some of the best photos and illustrations, and for that reason alone they’re nice to have.
One bittersweet thing about cicada books is people often resell them after a periodical cicada emergence is over, but that also means you can get them for a low price if you don’t mind a used book. Before Amazon.com was invented, people went to a place called the library, and an entire town essentially shared a single used book.
Cicadas Strange and Wonderful by Laurence Pringle illustrated by Meryl Henderson
This is a recent book and features page after page of color illustrations of cicadas, and cicada-related information. The book is factually accurate and the illustrations are excellent. The reading level is 4 to 8, but I think cicada fans of all ages would enjoy this book. Get it on Amazon.com.
Cicadas, A True Book, by Ann O Squire
The Visual Book of Australian Cicadas by Peter Leyden
This short book is packed with excellent illustrations of Australian cicadas. It is likely out of print, but I recommend it for the quality of the illustrations and the collectibility factor.
Cicadas and Aphids What They Have in Common by Sara Swan Miller
This book features photos (not illustrations) of cicadas and other members of the order Hemiptera (true bugs). I recommend this book for kids who want to expand their interest in insects beyond cicadas. The reading level is 8 or above.
The next three books are very similar in that they all feature photos of mostly periodical cicadas (Magicicadas) with easy-to-understand explanations. The reading level for all three is 4 to 8.
