Sweden: Gtl. and G. Sand. only. There is an old unverified record for Ostfold in Norway. - In Britain locally in Kent, Wight, Hants and Dorset. - Range: sparsely distributed from Spain to Czechoslovakia and North Italy to Sweden. Biology. This is a rather uncommon ground nesting species. In Britain where it has been well studied by Donisthorpe (1927) it is found nesting in dry peat or among smal stones and heather roots in small colonies of 50-100 workers and single queens. Ala are present in the nests during July. : Published as part of Collingwood, C.
