REVIEW BY DR. RONALD L. RUTOWSKI, Ph.D., ARIZONA STATE UNIVERSITY SCHOOL OF LIFE SCIENCES
This
guide by Dr. Phil McNally is a great addition to the butterfly identification
resources available for North America. It
covers a very restricted geographical area, the Central Highlands of
Arizona. Of over 700 species of
butterflies that have been recorded in North America, over a quarter of those
have been seen in the Central Highlands.
This
relatively narrow band runs east to west across the middle of the state where
the elevation changes rapidly between the broad flats of the Sonoran Desert and
the extensive evergreen forests on the northern plateaus. This band contains a surprising diversity of
habitats and so a surprisingly diverse array of butterflies. Dr. McNally does a great job of introducing us
to the biogeographical history of the Central Highlands, the butterfly and
plant communities found there, and their contributions to Arizona’s
biodiversity.
This
work also continues the effort to provide guides that support butterflying; that is, watching
and identifying live butterflies without collecting them. This guide features
species accounts and wonderful photographs in nature that clearly show the distinctive
markings for each species. I also appreciate that the author explains with
examples how limited collecting allows observations of anatomical structures
and UV color patterns that would otherwise not be possible.
This book will be a boon for both experts wanting to learn about this fascinating region in Arizona, as well as for the many people who visit the Highlands to enjoy their many recreational opportunities, including butterflying.
