This Guide to British Bumble Bees is presented by the Natural History Museum in London. For beginners, the site offers the Quick Guide to the Big Six Species which "are widespread and abundant throughout most of lowland Britain." The Quick Guide is also available in a downloadable Wallet Card format for easy reference. The site contains concise, descriptive information about all British bumble bee species including B. lapidarius (aka Stone Humble-bee), B. rupestris (aka Hill Cuckoo-bee), B. terrestris (aka Large Earth Humble-bee), B. pratorum (aka Early-nesting Humble-bee), and more. In addition, the website offers a clever system for identifying species by color pattern. Site visitors will also find an interesting segment on the Distribution and Decline of British Bumble Bees.
