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 20% of wildlife watchers report a Hunt's Bumble Bee sighting in Denver on a given day, based on 620 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 461 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Hunt's Bumble Bee in Denver on a given day, against under 5% in November to February, the lowest months. That is one of Denver's wettest months, with about 60 mm of rain against 15 mm in January.
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.
3rd of 4
Of the 4 cities where we can rate Hunt's Bumble Bee sightings, Denver ranks 3rd at about 20%. The best odds are in Calgary (Canada, about 30%) and Salt Lake City (United States, about 30%).
Same genus: Bombus
The closest relatives of the Hunt's Bumble Bee that you can see in Denver (genus Bombus, Bumble Bees) are Golden Northern Bumble Bee (about 20%), Brown-Belted Bumble Bee (about 20%) and American Bumble Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hunt's Bumble Bee is recorded against all the insects logged in Denver (620 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.
