The wings are black or very dark brown, while the membrane between the legs is relatively small and covered in hair.

Its tongue is long and narrow, with a pointed tip covered with fine papillae that help to draw up nectar when it feeds.

[citation needed] Geoffroy's tailless bat is found from northern Mexico, through much of Central America, across northern South America, and through Peru to parts of Bolivia and Brazil immediately south of the Amazon Basin.

[2] Three subspecies are currently recognised: The bat is primarily insectivorous, with up to 90% of its diet consisting of moths and beetles,[2] as well as other arthropods.

[8] Mating in Geoffroy's tailless bats seems to take place primarily between March and August, corresponding with the rainy season and allowing the young to be born when food is most abundant.
