Native to much of the United States except for the Southwest, and to the southernmost regions of several of the provinces of Canada. This is a common species in much of its wide range. Unlike many bumblebees in North America, it has experienced an average decline of 0%, and in some areas its populations may be increasing. It apparently faces no serious threat

This species nests underground or on the surface. Nests are generally small colonies of fewer than 50 workers, but they aggressively defend their establishments. This is a eusocial bee, one that forms a colony that works together to rear young with labor divided amongst reproductive and non-reproductive castes. All the daily tasks in the nest are performed by worker bees of all age groups,
