Formerly Leptonycteris curasoae. Also, formerly Sanborn's Long-Nosed Bat (Leptonycteris sanborni). Wt=15-25g, L=2.75-3.25" (69-84mm). Overall tan with dark wings. The
only bat that has a noseleaf and no visible tail.
NATURAL HISTORY: Feeds mostly on nectar and pollen (augmented by cactus
fruit when available). Nocturnal. Migratory, following the blooming of
cardon, organ pipe cactus, and saguaro north from Mexico into AZ and NM
in the late Spring and then following the blooming of agave south back
into Mexico in the Fall. Mating likely occurs before migrating north.
Upon arrival here, the females form huge maternity colonies in caves and
abandoned mines, where they give birth to their single offspring. Meanwhile,
males form groups of only a few individuals. These bats often form feeding
flocks that spend the night alternately feeding and roosting (in small
caves or human structures) together. The Lesser Long-Nosed Bat is listed
as Threatened in both Mexico and the U.S. See Bat
