So far, this the best field guide for amateurs and advanced naturalists alike. It contains many more species than seen in other books I have purchased on butterflies. It is is excellent that Kaufman and Brock gave their efforts to photograph so many specimens, even some of the rarest species. One the rare butterflies, the best descriptions to identify them are given. If you think you've found an uncommon butterfly, consult this book. You will know, believe me. Stating that this is geared toward amateurs only is a complete understatement. Butterflies Through Binoculars is great, but this equals the other one, in specifics, photo quality, and field identification! Thank you Ken Kaufman.

This book is very helpful for finding the names of the butterflies you find. It's color marked pages help you find them fast. It has range maps an colors on the range maps so you know what season thay fly. It tells you what larval food thay eat.The butterflies are listed in groups. If you want to know more about butterflies you will like this book. I use this book almost every day.

This is a great reference book for identifying butterflies. I especially liked the detailed photos and illustrations that showed butterflies as they would generally appear in nature. Other books often show the butterfly with wings open, but not with wings folded up, for example. This book shows both, including the differences between male and female butterflies and other details, so it makes it easy to compare your photo with the book's. I strongly recommend this book to anyone who takes lots of butterfly photos and wants to identify what you've photographed.
