Biology. This is a little known rare Central European species. It is a bark inhabitant and Forsslund (1957 a) found it nesting in old oak trees inhabited by Lasius brunneus (Latr.). Only worker samples were seen. Douwes (1976 a) records workers taken on Gland on oak and in a fallen branch. The species appears to be closely related to L. nylanderi which has similar habits.
