Liometopum

Biology
Species of this genus are found in the Holarctic Region as far south as southern México. This genus is very common in New Mexico; nests are usually located under stones or in living trunks or dead logs. Colonies are very large, probably numbering in the thousands or tens of thousands. The ants are very aggressive, and although they do not sting, they can be very unpleasant. (Mackay and Mackay 2002)
