Wisconsin Native Bumble Bees

Bumble bees are important pollinators that usher in the start of spring and remind us of bright, warm summer days. In recent years, several of the species that occur in Wisconsin and the Midwest have been in decline. A host of factors including loss of flowers, expanding agriculture, diseases and parasites, as well as altered weather patterns have all taken their toll on these essential insects.
