The broken-belted bumblebee or Ilfracombe bumblebee (Bombus soroeensis) is a species of bumblebee present in most of Europe and parts of Asia. This relatively small bumblebee has a rather oblong face and a proboscis of medium length. The body of the female is black with two yellow bands, one at the collar, one at the second tergite (abdominal segment). The latter often has black hair in the middle, thus dividing it into two. In males, the yellow abdominal band is broader, and usually covers most of the first tergite, as well as the second. On both sexes, the tail is white, often mixed with orange-yellow hairs. On the northern Scottish form, the female usually has an entirely white tail. Melanic forms can be found on the European continent. The bee reaches an average length of 16 mm (0.63 in) (queen, wingspan 30 mm (1.2 in)), 12 mm (0.47 in) (worker), and 13 mm (0.51 in) (male).
The nest, which at most has about 80 to 150 workers, is usually underground. At least in Britain, the bumblebee seems to favour uplands, heaths, and grasslands. Favourite flowers are clovers, ling, harebell and Scabiosa as bird's-foot trefoils.

Rare
Under 5% of wildlife watchers report a Broken-Belted Bumble Bee sighting in Pyrénées National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 738th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and August–September
In those months about 10% of wildlife watchers report a Broken-Belted Bumble Bee in Pyrénées National Park on a given day, against under 5% in July and October–May, the lowest months.

GBIF citizen-science records
It is estimated from how often the Broken-Belted Bumble Bee is recorded against all the insects logged in Pyrénées National Park (11 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.
