More than ever before, there is widespread interest in studying bumble bees and the critical role they play in our ecosystems. Bumble Bees of North America is the first comprehensive guide to North American bumble bees to be published in more than a century. Richly illustrated with color photographs, diagrams, range maps, and graphs of seasonal activity patterns, this guide allows amateur and professional naturalists to identify all 46 bumble bee species found north of Mexico and to understand their ecology and changing geographic distributions. The book draws on the latest molecular research, shows the enormous color variation within species, and guides readers through the many confusing convergences between species. It draws on a large repository of data from museum collections and presents state-of-the-art results on evolutionary relationships, distributions, and ecological roles. Illustrated keys allow identification of color morphs and social castes.

California is home to over sixteen hundred species of undomesticated bees—most of them native—that populate and pollinate our gardens, fields, and urban green spaces. In this absorbing guidebook, some of the state's preeminent bee and botany experts introduce us to this diverse population. California Bees and Blooms holds a magnifying glass up to the twenty-two most common genera (and six species of cuckoo bees), describing each one's distinctive behaviors, social structures, flight season, preferred flowers, and enemies. Enhancing these descriptions are photographs of bees so finely detailed they capture pollen scattered across gauzy wings and iridescent exoskeletons. Drawing from years of research at the UC Berkeley Urban Bee Lab, California Bees and Blooms presents an authoritative look at these creatures, emphasizing their vital relationship with flowers. In addition to opening our eyes to the beautiful array of wild bees in our midst, this book provides information on fifty-three bee-friendly plants and how to grow them. Just a few square feet of poppies, sage, and phacelia are enough to sustain a healthy population of wild bees, transforming an urban or suburban garden into a world that hums and buzzes with life.
