Bombus huntii is a species of bumblebee. It is native to western North America, where it occurs in western Canada and the United States as far east as Ontario and Minnesota, and in Mexico as far south as the Trans-Mexican Volcanic Belt. It is known commonly as the Hunt bumblebee or Hunt's bumblebee. This bee's whole genome has been recently sequenced as part of the Beenome100 project.
This bee lives in desert scrub, prairies, and meadows. In the southern part of its range in Mexico it lives in pine ecosystems and it can be found at high elevations, such as the tops of tall volcanoes. The bee is active in summer and fall, and in Mexico it flies throughout much of the year. It nests underground in colonies consisting of a queen, workers, males, and new queens. Colonies only last one-year, with only mated queens overwintering.
Food plants visited by this species include rabbitbrush, thistles, sunflowers, penstemons, phacelias, currants, rudbeckias, and clovers. This species has experienced declines, but it is still one of the more common bees of western North America.
This bumblebee is susceptible to certain viruses that infect honey bees, such as Black Queen Cell Virus (BQCV) and Deformed Wing Virus (DWV). Experiments suggest that this and other native species make efficient pollinators of crop plants such as tomatoes, and that commercial rearing would be a viable alternative to introducing non-native bees for the purpose.

Possible
About 30% of wildlife watchers report a Hunt's Bumble Bee sighting in Salt Lake City on a given day, based on 482 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 242 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July and August
In those months about 50% of wildlife watchers report a Hunt's Bumble Bee in Salt Lake City on a given day, against under 5% in December to February, the lowest months. Those are among Salt Lake City's driest months, with about 25 mm of rain a month against 70 mm in December.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Hunt's Bumble Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Hunt's Bumble Bee sightings, Salt Lake City ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Calgary (Canada, about 30%).
Same genus: Bombus

GBIF citizen-science records
It is estimated from how often the Hunt's Bumble Bee is recorded against all the insects logged in Salt Lake City (482 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
