Conservation Status: Endangered.

The Mexican long-nosed bat feeds mainly on the nectar and pollen of agaves, and is found in Texas in June and July, when the plants are in bloom there. Then it migrates southward into Mexico, where it lives in pine-oak forests and deserts. It may be the main pollinator of a plant that has economic value in Mexico, the pulque plant. Little is known about the bat's pattern of reproduction. Nursing females and juvenile bats have been seen in Texas in June and July.
