Rusty-Patched Bumble Bee

The Rusty-Patched Bumble Bee (Bombus affinis) is a vital native pollinator of the eastern United States and Upper Midwest, famed for its key role in maintaining wildflower diversity and agricultural productivity. Once a common sight buzzing through grasslands, orchards, and gardens, this species has tragically suffered a catastrophic decline of over 87% in recent decades. As the first bumble bee species to be listed under the U.S. Endangered Species Act, it serves as a powerful symbol for insect conservation efforts across North America. These bees are highly social insects that form annual colonies. In early spring, solitary queens emerge from underground winter hibernation to establish new nests, typically in abandoned rodent burrows. Throughout the summer, diligent workers forage tirelessly, utilizing complex flight and sensory capabilities to gather nectar and pollen. By supporting this delicate pollinator, we protect entire ecosystems that rely on their highly efficient pollination services.
