Bombus terricola, the yellow-banded bumble bee, is a species of bee in the genus Bombus. It is native to southern Canada and the east and midwest of the United States. It possesses complex behavioral traits, such as the ability to adapt to a queenless nest, choose which flower to visit, and regulate its temperature to fly during cold weather. It was at one time a common species, but has declined in numbers since the late 1990s, likely due to urban development and parasite infection. It is a good pollinator of wild flowers and crops such as alfalfa, potatoes, raspberries, and cranberries.
B. terricola belongs to the order Hymenoptera, which consists of ants, bees, wasps, and sawflies. B. terricola belongs to the family Apidae, which encompasses bumble bees, honey bees, stingless bees, and more. Within this, it is part of the genus Bombus, which consists of bumble bees. Kirby first defined this species in 1837. Bombus occidentalis has been speculated to be a subspecies of B. terricola, but most experts now agree that it is its own distinct species. B. terricola is also closely related to B. affinis both phylogenetically and in terms of pheromone signalling... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow-Banded Bumble Bee sighting in Toronto on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 427th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow-Banded Bumble Bee in Toronto on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Yellow-Banded 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 Yellow-Banded Bumble Bee sightings, Toronto ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%) and Edmonton (Canada, under 5%).

GBIF citizen-science records
It is estimated from how often the Yellow-Banded Bumble Bee is recorded against all the insects logged in Toronto (42 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.
