The heath humble-bee or small heath bumblebee, Bombus jonellus, is a species of bumblebee, widely distributed in Europe and northern Asia, as well as northern North America. A fairly small bumblebee, it has body lengths around 16 mm (0.63 in) (queen) and 12 mm (0.47 in) (worker and male). The queen has an average wingspan of 29 mm (1.1 in). The face and proboscis are short. Females (queens and workers) have a predominantly black abdomen with a yellow collar, the first and sometimes second terga yellow, and a white tail. The face is black, occasionally with a patch of yellow fur on the top. Males are similar, but with more yellow; the yellow collar continues on the ventral side, the two first terga are always yellow, and much more yellow fur is found on the face. However, darker forms of the females are seen, as well as forms (sometimes considered subspecies) that differ in the amount of yellow in the fur, and with brownish hairs on the white tail. On the Orkney and the Hebrides, a form exists where the males have red tails instead of white.... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Heath Bumble Bee is recorded against all the insects logged in Bavarian Forest National Park (8 verified sightings from 2019 to 2026), 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.
