Specimen labels

This species nests deep in the ground often among shrub roots and under deep boulders, but occasionally also constructs mound nests of fine loose soil. Alatae fly in August and September and fertilised queens are thought to found fresh colonies through adoption by Lasius alienus and Lasius niger but actual recorded instances are very few or dubious. Dealate queens are often found wandering singly above ground in spring (Collingwood, 1979).
