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.A landmark publication, Bumble Bees of North America sets the standard for guides and the study of these important insects.The best guide yet to the 46 recognized bumble bee species in North America north of MexicoUp-to-date taxonomy includes previously unpublished results Detailed distribution maps Extensive keys identify the many color patterns of species 410 0$aPrinceton Field Guides 606 $aBumblebees 606 $aBumblebees$zUnited States$vIdentification 606 $aBumblebees$zCanada$vIdentification 606 $aBumblebees$zUnited States$xGeographical distribution 606 $aBumblebees$zCanada$xGeographical distribution 615 0$aBumblebees. 615 0$aBumblebees 615 0$aBumblebees 615 0$aBumblebees$xGeographical distribution. 615 0$aBumblebees$xGeographical distribution. 676 $a595.799 700 $aWilliams$b Paul H$0309363 702 $aThorp$b Robbin W.$f1933- 702 $aRichardson$b Leif 702 $aColla$b Sheila 712 02$aCredo Reference (Firm), 801 0$bMiFhGG 801 1$bMiFhGG 906 $aBOOK 912 $a9910827877103321 996 $aBumble bees of North America$93932098 997 $aUNINA
