Geographic Range [top]

Range Description: This species occurs from Chiapas, Mexico, and Belize, is patchily distributed through Honduras and the rest of Central America (not recorded in Nicaragua), to south Peru, Bolivia and southeastern Brazil, but appears to be absent from dry deciduous forest over much of southeastern Brazil (Eisenberg, 1989; Reid, 1997). Lowlands to 2,600 m (Emmons and Feer, 1997). However, it has recenty captured in Pantanal and Cerrado (Aguiar pers. comm.).

Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Poorly known. It is strongly associated with multistratal tropical evergreen forests but is broadly tolerant of man-made clearings in Venezuela (Handley, 1976).This mixed feeder will take fruits as well as insects. It has been recorded feeding on larvae and pupae, and from the nest of a social wasp. One individual caught in Costa Rica had eaten fruit, especially those of cucurbit vines (LaVal, 1977). One was collected while it was attacking a large rat, apparently a Proechimys. Females bear a single young. These bats are found around streams and swamps or marshes. It is usually captured in mist nets set over streams in evergreen forest. The roost is undescribed (Emmons and Feer, 1997).
Systems: Terrestrial

Threats [top]

Major Threat(s): No major threats throughout its range.
