Tribe LASIINI 



Genus LASIUS Fabricius 



Ants of this holarctic genus nest in exposed soil, under objects or in rotting wood. Colonies are 

 small to moderate in size. Workers attend and may foster honeydew-excreting insects. The 

 treatment here follows the revision by Wilson (1955).

 B. C, Mont., Idaho, Wash., Oreg., Calif., S. Ariz.; Mexico; Eurasia. Ecology: In N. Amer., 

 this ant shows a preference for well-shaded woodlands where it nests in rotting logs 

 and stumps or under stones. Only occasionally has it been found in open areas. In the 

 early American literature, this species has been recorded as americanus Emery, and 

 alienus has commonly been confused with neoniger. A frequent house pest. Cornfield 

 ant is the approved conunon name for alienus.
