The Bees in Your Backyard: A Guide to North America's Bees.
By Joseph S. Wilson & Olivia J. Messinger Carril Princeton University Press, 2015
A wonderfully written, richly and attractively illustrated book, mostly with the authors' own excellent images!
This is a wonderful introduction to North America's over 4000 native bee species. The title page's photos communicate at once the great diversity of our bee fauna.
A MUST for everyone who wants to learn about the bees that have evolved with our flora, as well as a useful reference for professionals.
