Bombus vosnesenskii, the yellow-faced bumblebee, is a species of bumblebee native to the west coast of North America, where it is distributed from British Columbia to Baja California. It is the most abundant species of bee in this range, and can be found in both urban and agricultural areas. Additionally, B. vosnesenskii is utilized as an important pollinator in commercial agriculture, especially for greenhouse tomatoes. Though the species is not currently experiencing population decline, urbanization has affected its nesting densities, and early emergence of the B. vosnesenskii has been implicated in the increasing lack of bee diversity on the West coast.
The genus name Bombus – the bumblebee – comes from the Latin word which means a buzzing or humming sound. There are 250 species split into 38 subgenera within the genus Bombus. These subgroups share similar morphologies, despite their varied habitats and behavioral patterns. However, many of the groups are monophyletic based on the distinct genitalia of the male bee. Genetic studies have revealed the bumblebee to be closely related to the sting-less bee and the honey bee.

It is the 36th most-seen of the 851 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January to August
In those months about 10% of wildlife watchers report a Yellow-Faced Bumble Bee in Los Angeles on a given day, against under 5% in September to December, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Yellow-Faced 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.

GBIF citizen-science records
It is estimated from how often the Yellow-Faced Bumble Bee is recorded against all the insects logged in Los Angeles (835 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.
