Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
One of the smaller subfamilies of ants, with most species found in the tropical regions of the world. Most of the North American forms are either northern extensions of Neotropical taxa or have been introduced by commerce from other parts of the world. These are primitive ants which nest in small colonies of a few hundred individuals or less, mostly in soil or rotting wood. They are predaceous and carnivorous.
