Temnothorax americanus
''Temnothorax americanus'' is a species of slave-maker ant in the genus ''Temnothorax''. The ants are 2–3 mm in size, and endemic to the northeastern United States and adjacent Canadian regions.〔Social Insects Specialist Group 1996. (''Protomognathus americanus'' ). (2006 IUCN Red List of Threatened Species. ) Downloaded on 10 August 2007.〕 ''T. americanus'' is a species of slave-maker ant. They do not forage for food, but instead 'scout workers' from the colony seek out nearby host colonies of ants, steal larvae and bring them back to their own colony. A small ''T. americanus'' colony could consist of a queen, two to five workers and thirty to sixty slaves.
In a study published in ''Animal Behaviour'', researchers showed that ''T. americanus'' scouts target stronger colonies over weaker ones to steal larvae from.〔
It was formerly placed as the sole member of the genus ''Protomognathus''.〔
