Current distribution of non-native bumblebees (Hymenoptera, Apidae) on the Faroe Islands including the first records of three recent arrivals

Three new non-native bumblebee species, Bombus hortorum, Bombus hypnorum
and Bombus terrestris, have been recorded on the Faroe Islands for the first time.
Previous literature reported only the presence of Bombus lapponicus, Bombus
lucorum and Bombus pratorum. A combination of records from 2007 to 2024 have
been utilised to explore and update the distributions of each species of bumblebee
now present. Whilst B. lucorum has continuously spread through most of the
islands, B. pratorum, B. hortorum and B. hypnorum have remained localised with
limited range increase. The confirmation of an individual B. terrestris is discussed
with respect to misidentifications. B. lapponicus is considered no longer present on
the islands. These updated distributions provide initial data to understand the ongoing
colonisation of these bumblebee species, the potential for further establishments or
range expansions, and will help to determine their invasive potential in the future.
