Due to their large size and dense hair covering their entire body, bumble bees can fly and pollinate in cooler temperatures and carry more pollen than other bees. They are also active the entire length of Wisconsin’s growing season, from April to October.
Bumble bees are social bees, living in underground colonies with anywhere from 50 to 500 individuals.
