Brown-Belted Bumble Bee (Bombus griseocollis) lives in eastern North America across United States (except Southwest) and southern Canada. Its conservation status is Least Concern.
Fascinating facts about the Brown-Belted Bumble Bee
- The brown-belted bumblebee has been recorded more than 100 stories up on the Empire State Building, showing its willingness to fly at extreme urban heights. It also serves as a common pollinator in community gardens across New York City, helping urban growers.
- Male brown-belted bumblebees assist in warming pupae, a role usually limited to workers, by wrapping their bodies around the cocoon and pumping their abdomen. Although they cannot raise the temperature as high as queens, they can maintain a raised temperature that aids development. Multiple bees, male or female, may incubate an egg at the same time, increasing efficiency.
- Like many insects, brown-belted bumblebees may be attacked by parasites such as conopid flies, which normally force their victims to dig their own graves. Remarkably, only 18% of these bumblebees succumb to conopid mind control, a quarter of the rate seen in other bumblebee species.
- Brown-belted bumblebee colonies are modest in size, typically containing fewer than fifty workers. Despite their small numbers, the bees defend their nests with notable aggression, warding off intruders and predators. Nests may be constructed either below ground or on the surface, depending on the local environment. This flexible nesting habit allows the species to thrive in diverse habitats such as meadows, wetlands, farms and even dense urban areas.
- Male brown-belted bumblebees are relatively small, measuring between 1.5 and 1.9 centimetres in length with an abdomen width of about 0.7 centimetres. Their most striking feature is the exceptionally large eyes, which span roughly two thirds of the head's width, giving them a broad field of vision. These visual adaptations support their mating behaviour, as males perch and wait for passing young queens.

About the Brown-Belted Bumble Bee
As the warm sunlight dances across the lush meadow, the Brown-Belted Bumble Bee bursts into life, its fuzzy body a blur of motion as it darts from bloom to bloom with an irrepressible energy. With a nimble precision, it navigates the intricate landscape of petals and stamens, collecting nectar with an industrious zeal that is both captivating and essential to the very survival of the ecosystem. As it flies, its brown belt glistens like polished leather, a subtle yet striking hallmark of a creature that is at once humble and extraordinary.
