Global Range: (200,000 to >2,500,000 square km (about 80,000 to >1,000,000 square miles)) Widespread in southern Canada and much of the U.S., with reports as far south as northern California and Florida. Not reported in southern Arizona. It is occurs at low elevations even in the South, and is apparently rare in the Great Smoky Mountains (Super and Moyer, 2003).

Comments: Many kinds of flowery places including prairies, croplands, meadows, urban gardens.

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Reasons: As far as what is known, this is still a widespread bumble bee that is common in many parts of its range. No reports of decline.

Intrinsic Vulnerability: Not intrinsically vulnerable

Environmental Specificity: Broad. Generalist or community with all key requirements common.

Global Short Term Trend: Relatively stable (=10% change)

Comments: Colla and Packer (2008) found this species to be uncommon, but with no change in abundance, and Williams et al. (2009) give it a slightly negative decline measure, indicating a possible minor increase. It was the second most abundant species in Grixti et al. (2009) samples during 2007. I is not reported as declining in Vermont or listed as declining by the Committee on the Status of Pollinators in North America (2007), or by Xerces etc., and is apparently still common in South Dakota (Johnson, 2009) and Missouri (Missouri Natural Heritage Program). Matteson and Langellotto (2009) report this bee to be common early in the season in New York City community gardens.

Global Long Term Trend: Decline of 30-50%

Comments: Obviously some loss of habitat, but this species persists in very urban parts of New York City.

Degree of Threat: Low

Global Protection: Very many (>40) occurrences appropriately protected and managed

Comments: Tentative. Occurs on many protected lands, possibly needs protection from unknown factors.
