Feeds on nectar, insects, and probably succulent fruits and pollen (Griffiths and Gardner, 2008). Probably roosts in small groups in hollow trees and in small caves. Based on the recent restriction of L. mordax (see Moratelli and Dias, 2015), the species occurs in the Atlantic Forest–Caatinga ecotone (agreste), and along the eastern border of the Caatinga (sertão). It is found in tall, humid forest. In the northeastern part of its range, it occupies very specific habitats - high plateaus that sustain humid forest in generally semi-arid regions.

The species is endemic to southeastern Brazil (Simmons 2005), where it is widespread. However, the recent description of L. inexpectata by Moratelli and Dias (2015) restricts the distribution to just three localities from eastern Brazil, at Bahia and Sergipe states.

The species-specific habitats, especially in the eastern part of the range, need to be protected. Because of the recent split of L. mordax by Moratelli and Dias (2015), a taxonomic assessment could be necessary.
