Bumble bees all belong to the genus Bombus in the family Apidae, the same family as honey bees, digger bees, squash bees, orchid bees, and stingless bees. They have special adaptations for colder weather including their long, thick hair, and are more commonly found in colder climates. Minnesota is home to 23 of the 45 species known from North America. Bumble bees have an annual colony life cycle, starting with the emergence of queens in the spring, colony founding, production of workers, growth of the colony, production of males and queens, mating, and ending with hibernation of newly mated queens.
Bumble bees are better studied than many other native bees, so we know more about their conservation status. Unfortunately, in North America 1 out of 3 species is in decline. The causes of these declines are thought to include habitat loss, pesticides, pathogens, and climate change. Minnesota bumble bee species thought to be in decline include Bombus affinis, Bombus bohemicus, Bombus fervidus, Bombus fraternus, Bombus pensylvanicus, Bombus terricola, and Bombus variabilis.
On March 21, 2017, the rusty patched bumble bee, Bombus affinis, became the first bee in the continental U.S. to be given protection by the US Fish and Wildlife Service as an endangered species. Visit the USFWS to get the latest updates on where rusty patched bumble bees have been found and what we can do to help protect them. Minnesota is one of the few places on the planet where we can still find rusty patched bumble bees. We all can help them by planting flowers they prefer, creating nesting habitat by leaving corners of your yard untended and creating woodpiles, and keeping flowers and potential nesting sites free of pesticides. Help scientists and conservationists track populations be joining citizen science efforts to track bumble bees.
