This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Population [top]

Population:The species is locally common. The species shows a strong preference for palm trees (and secondarily for palm-frond-thatched roofs) as day roosts and palms may be a critical habitat element (Kurta and Lehr 1995). They may be disappearing as the native trees get lost (Barquez et al. 1999).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Lasiurus ega occurs in a variety of habitats, in both mesic and xeric forests (Kurta and Lehr 1995). In Venezuela, this bat lives in tropical dry forest, subtropical moist forest, and tropical moist forest (Handley 1976). Mostly, these bats roost in trees, generally hanging from the midrib of a leaf, and among dead fronds of palms trees, but also in building crevices or holes. In the U.S. L. ega is associated with introduced palms, which is thought to be a reason for its recent expansion northward. They can be found alone or in groups with up 20 individuals. They can be found in degradeted areas and roofs made with palm (Barquez et al. 1999). In Mexico, this bat apparently eats beetles more frequently than other preys (Kurta and Lehr 1995).

Threats [top]

Major Threat(s): No major threats are known for this species.
