help Bombus griseocollis FAQ
Why is Bombus griseocollis called the brown-belted bumble bee?
Workers and queens commonly show a rusty brown band across the second abdominal segment, behind a yellow first segment. The amount of brown can vary, so identification also relies on body structure and the complete color pattern.
Where does the brown-belted bumble bee live?
Bombus griseocollis occurs across much of the United States and southern Canada, especially in open habitats. It is frequently found in meadows, farms, gardens, and urban areas rather than deep forest.
Where does Bombus griseocollis build its nest?
Colonies commonly nest at or just below ground level in cavities such as abandoned rodent nests. Like other bumblebees, a single overwintered queen establishes a new annual colony in spring.
Which crops does Bombus griseocollis help pollinate?
The species visits many wildflowers and crops, including clovers, sunflowers, and members of the squash family. Its broad diet makes it a useful generalist pollinator across agricultural and suburban landscapes.
