Mexican long-nosed bat is one of the rarest mammals recorded in Texas, with just 127 documented encounters, all from the Trans-Pecos borderlands around Big Bend National Park, Guadalupe Mountains National Park, and the Davis Mountains. Texas sits at the very northern edge of a species whose real stronghold is central Mexico, and NatureServe rates it Critically Imperiled (S1) here, the most serious rank the state assigns, even though the global IUCN listing is a less severe Endangered.

The Texas record set is too sparse to show a reliable seasonal pattern; most of what exists concentrates in July, tied to when agaves bloom and this nectar-feeding bat follows the flowering trail north across the border. A long muzzle and brush-tipped tongue let it drink from tall agave flowers while carrying pollen between plants, work that depends on connected blooms along its migration route, not just a safe roost. Sparse Texas records likely reflect how hard this bat is to detect, not how rare it truly is here.
