This book starts off with a pictorial table of contents which is great for those looking to narrow down butterfly identification.
There is a primer on butterfly identification: size, shape, posture and flight style. Variation, habitat and season, range maps, location tips and the butterfly life cycle are also included.
Color page tabs coincide with the color coded table of contents and allows for easy thumbing to locating the seven butterfly families and their subfamilies. There are about 2,300 digitally edited/enhanced photographs of the butterflies.
This book is designed in facing-page format. The left side provides the common name, scientific name, a range map and flying season and broods. A description of each butterfly is provided with details pointed out for differentiating the sexes and similar species. Each entry indicates the larval foodplant.
The right page reflects digitally edited/enhanced ventral and dorsal photographs of each butterfly with a life size silhouette. Identifying marks are also pin-pointed for emphasis between the sexes, regionally distinct forms and similar species.
This book concludes with an index of larval food plants by common name and scientific name noted. An index of the scientific names of butterflies follows. Best of all is an index of English names which doubles as a life list!!!
The final page is a color coded alphabetical quick reference guide of butterflies.
This book easily fits into my camera bag and I never leave home without it!!! I've also seen many butterfliers walking around with their own copy tucked into their back pocket! It's great to be out in the field during our butterfly festival season and see everybody reach for their guide book when we spot a butterfly we aren't able to easily identify :o)
