Genus PARATRECHINA Motschulsky 



Species of this genus often nest in the soil where the entrance may be surrounded by a small

 Because of the differences of opinion in recent literature regarding the status of subgenera, par-

Type-species: Paratrechina currens Motschulsky. Desig. by Wheeler, 1911. 



longicomis (Latreille). S. C. s. to Fla. w. to Tex.; Calif.; Pantropical. Ecology: Highly adaptable 

 and may nest in many situations such as trash, refuse, plant cavities, rotting wood, and 

 in soil under stones. Workers are omnivorous and feed on live and dead insects, seeds, 

 honeydew and household foods. Sometimes a household pest. Introduced into the U. S. 

 Probably native to Africa or the Orient and spread to many parts of the world by
