[4] The tailed tailless bat is found in Bolivia, southern and northeastern Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Venezuela, and the extreme northern tip of Argentina.

[7] Since they are able to maintain their body temperatures even in relatively cool weather, they require a high calorific intake for their size, and must spend at least four hours every night feeding.

Studies have generally found fertile adults between August and November, during the rainy season, and infertile individuals at other times of the year, although with some exceptions.

[4] The tailed tailless bat is nocturnal, spending the day roosting in caves, tree hollows, and some man-made structures.

They are omnivorous, using their long tongues to lap nectar from flowers, but also eating some small beetles, bugs, and lepidopterans.
