Nineteen species of bumble bee are historically from Ohio, but only about 10 are now frequent. Some were never common here, but several once abundant species are now in steep declines. Indeed, two species are in danger of becoming extinct not only in our state, but globally. One of those species (Bombus affinis) has not been seen in Ohio since about 2002. Habitat loss, introduced parasites and pesticide use are the most likely causes of these declines. Good habitat management can help them recover in some cases.
