This species is listed as Least Concern because it is widely distributed and unlikely to be declining at a rate which would qualify it for inclusion in any of the threatened categories.
Previously published Red List assessments:
2008 Least Concern (LC)
1996 Lower Risk/least concern (LR/lc)

Geographic Range [top]

Range Description: This species is broadly distributed from Oaxaca and Veracruz (Mexico) south to southeast Brazil, Bolivia, Peru and Ecuador, Trinidad and perhaps New Providence Island (Bahamas; see Jones and Carter 1976, Simmons 2005). This species occurs in the lowlands and it has not been taken above 1,500 m asl (Reid 1997). It also occurs in Nicaragua (Medina et al. in press).

Population [top]

Population: It is uncommon but widespread. These bats may be geographically limited to areas with caves or rocks (Emmons and Feer 1997). It can be locally abundant near caves where roosting occurs with up to 500 individuals (Lassieur and Wilson 1989).
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It is strongly associated with moist habitats and is most frequently encountered in multistratal tropical forest (Eisenberg and Redford 1999). It is usually found in mature, evergreen forest, occasionally deciduous forest and agricultural areas (Reid 1997). This bat is an aerial and gleaning insectivore, it occasionally consumes fruits. It roosts in caves or tunnels, such as mine tunnels and forms colonies of 12 to 25, sometimes up to hundreds (Goodwin and Greenhall 1961, Reid 1997, Eisenberg and Redford 1999). Activity begins well after sunset, in full darkness. This bat is an extremely agile flier and may stop and hover in front of a mist net or escape through small gasps. It is sometimes caught in nets across streams or paths through forest (Reid 1997).
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): It is associated with cave and karstic habitats which may be threatened by disturbance within forests. In Bolivia this species is considered to be Vulnerable as it is not known from a protected area and it is in a fragile ecosystem.

Conservation Actions [top]

Conservation Actions: Conservation of caves and karstic habitats is the recommended conservation action. This species occurs in a number of protected areas throughout its range, including in Belize (Miller pers. comm.). In Mexico is listed as threatened under NOM - 059 - SEMARNAT - 2001 (Arroyo-Cabrales pers. comm.).
