Range DescriptionThis species is spread widely by attaching to livestock fur and thus the original range is difficult to define. Its native range is likely central and northern Mexico. Currently it is widely distributed in Mexico, the United States, and Colombia. The species is also reported from the literature from Cuba, Ecuador, Peru and Chile (Hernández et al. 2004). It is reported for the Mexican states of Aguascalientes, Chihuahua (R. Corral pers. comm. 2009), Coahuila, Guanajuato, Hidalgo, Jalisco, Nuevo León, Puebla, San Luis Potosí, Tamaulipas, and Zacatecas. In the Unites States it occurs in Texas (K. Heil pers. comm. 2009). It grows at elevations of 100 to 1,900 m asl.
