Natalus mexicanusMiller, 1902 is the smallest species of Natalus and is commonly called the Mexican greater funnel-eared bat. This insectivorous bat is the most widely distributed species of Natalidae, occurring from northern Mexico to Panama, inhabiting mainly deciduous and semideciduous tropical forests, generally at elevations below 300 m. N. mexicanus, a cave-dwelling bat, is considered as a “Least Concern” species by the International Union for Conservation of Nature and Natural Resources, and some data indicate moderate population sizes in several caves, although the population status at other sites is currently unknown.
