Range & Status
Mainly on coasts in southern Britain. A large, dark-winged black bee which nests, often colonially, in steep banks and walls. A large number of coastal sites, both north and south coasts, are now known, together with a few inland sites. Some of the colonies are very large, such as some of the sites on the Lizard Peninsula, with 10,000s of individuals. Cornwall remains one of the strongholds of this species in Britain today.
