A devote bug photographer, I became interested in leafhoppers about a year ago. It's easy finding specialty guides and books on popular insects, but not so for leafhoppers. This is the first book I've found available for leafhoppers. A large number of species have been named since this book was published in 1948. No problem.

This is NOT a field guide. This 376-page book is full of illustrations and descriptions to positively ID many of my local fauna. The descriptions are detailed for a better understanding this family, yet easily understandable by an amateur like me. You will not find a better leafhopper book for $30, sometimes available from Amazon.
