photograph © Alex Wild 2006

The arid American southwest has no native species of Strumigenys trap-jaw ants, but S. louisianae has been accidentally introduced to urban areas where they survive in irrigated lawns.  This species- only one or two milimeters long- is native from the southeastern United States south to Argentina.
