This list was compiled by first searching Formis 2002 for references with ‘Formica lepida’ in any field. The resulting list was edited to remove any entries that were dissertations, specific to pest control, concerned primarily with myrmecophiles or predators, or, generally judged to have marginal relevance to this ant species.
