On July 30, 1947, what appeared to be the nuptial flight of the above species occurred in the home of a resident of Windsor, Ontario. Hundreds of males and females appeared suddenly from the base of the toilet in the bathroom on the ground floor of the cottage and flew to the open screened window. Dr. William S. Creighton, who identified the species, has remarked that the choice of such a nesting site was certainly unusual for an ant which normally nests outdoors.
