Bombus lucorum

Bombus lucorum, the white-tailed bumblebee, is a species of bumblebee, widespread and common throughout Europe. This name has been widely used for a range of nearly identical-looking or cryptic species of bumblebees. In 1983, Scholl and Obrecht even coined the term Bombus lucorum complex to explain the three taxa (B. lucorum, Bombus magnus, and Bombus cryptarum) that cannot be easily differentiated from one another by their appearances. A recent review of all of these species worldwide has helped to clarify its distribution in Europe and northern Asia, almost to the Pacific. B. lucorum reaches the Barents Sea in the North. However, in southern Europe, although found in Greece it is an upland species with its distribution never quite reaching the Mediterranean.
Compared to other bumblebee species, the individuals of B. lucorum have shorter tongues, and this characteristic enable them to rob nectar. The worker bee uses the horny sheath around its tongue to make a hole through the flower, reaching the nectar without entering the flower. Therefore, the worker bee does not come in contact with the pollen while getting the nectar.

GBIF citizen-science records
It is estimated from how often the White-Tailed Bumble Bee is recorded against all the insects logged in Hamburg (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.
