Habitat and Ecology [top]

Habitat and Ecology: The species is associated with primary forest. Its activity is concentrated near streams or moist areas (Eisenberg, 1989). It roosts in hollow trees, buildings, and under bridges and feeds on insects, mainly katydids, cockroaches, June beetles, and Lepidoptera larvae, which are gleaned from vegetation. Fruit is taken during the dry season only (Whitaker and Findley, 1980; Wilson, 1971). This bat is attracted to katydid calls and is much more likely to be caught in mist nets baited nets (where it is seldom captured). Equal numbers of male and female (noncalling) katydid remains have been found at roosts, indicating that the bats can find prey using cues other than male songs.
Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation, although this is not considered as a major threat.
