The tree bumblebee or new garden bumblebee (Bombus hypnorum) is a species of bumblebee common [on] the European continent and parts of Asia. Since the start of the twenty-first century, it has spread to Great Britain and Ireland. These bumblebees prefer habitats that others do not, allowing them to pollinate flowers in areas that many other species do not get to.
Bombus hypnorum has a short proboscis and a rounded head. The thorax is usually of a uniformly ginger color (but examples with a darker, or even black thorax occur), the abdomen is covered in black hair, and the tail is always white. In workers, the first tergite (abdominal segment) is black-haired, but a proportion of males may have ginger hairs intermixed with the black hair, both on the face and on the first abdominal tergum. On the European continent, individuals with extended yellow coloration exist. Workers are often (but not always) small, while drones are much bigger in comparison. The queens vary in size.
Bombus hypnorum is part of the genus Bombus. Its closest genetic relatives are B. jonellus and B. sichelli. B. hypnorum is a common bumblebee species... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Tree Bumble Bee is recorded against all the insects logged in Vienna (87 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.
