Bombus distinguendus
Great Yellow Bumble Bee, great yellow bumblebee
Bombus distinguendus, the great yellow bumblebee, is a bumblebee species with a Palearctic distribution spanning northern and central Europe, northern Russia, and Alaska. The species has experienced significant population declines across much of its European range, with critically low numbers or local extinction in several regions. In Ireland, it is classified as Endangered and restricted to a single remaining population in the northwest. The species exhibits late-season phenology compared to other bumblebees and shows strong foraging preferences for specific plant species, particularly Common Knapweed (Centaurea nigra) in Irish populations.
