Bumble bees are some of our most abundant and recognizable pollinators, essential for the pollination of many native flowering plant species. As such, the diversity of bumble bees has a long history of study by both professionals and amateurs. Because of such extensive study, it is felt that new species of bumble bees are unlikely to be found. Outstanding controversies remain, however, in what comprises a given bumble bee species.
Twelve of the 50 bumblebee species in North America are listed as at-risk, some declining by almost 90 per cent in last two decades
