Agricultural field margins provide food and nesting resources to bumble bees (Bombus spp., Hymenoptera: Apidae) in Southwestern Ontario, Canada

Bumble bees are declining globally, largely due to habitat loss driven by agricultural intensification. Within agriculturally dominated landscapes, semi‐natural habitats (e.g. meadows, wetland edges) are fragmented, increasing the value of uncropped agricultural field margins for providing a source of food, nesting, and hibernation resources to bumble bees. We compared bumble bee communities sampled in agricultural field margins and semi‐natural...
