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.
