This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of 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.
|Range Description:||This species occurs from Sinaloa and Michoacan (Mexico) to Colombia, Guyana, Surinam, and French Guiana; Trinidad (Simmons, 2005). It occurs in lowlands to 2,400 m (usually below 1,000 m).|
Native:Belize; Colombia; Costa Rica; El Salvador; French Guiana; Guatemala; Guyana; Honduras; Mexico (Sinaloa); Nicaragua; Panama; Suriname; Trinidad and Tobago

|Population:||This bat is uncommon to locally common (Reid, 1997). Need acoustic survey, not as abuntant as M. rufus (Miller pers. comm.)|
|Habitat and Ecology:||Aerial insectivore. This species can be found in evergreen and dry deciduous forest, pasture, and populated areas (Reid, 1997). It roosts in caves and houses, often in large groups. In Costa Rica, 76 individuals were captured from a single roost (Timm et al., 1989). A long-term study in Yucatan, Mexico, found this species to be the most commonly encountered molossid in the region (Bowles et al. 1990). Individuals are most active during the first 2 hours after sunset and again before dawn. The diet consists mainly of moths, with some beetles and other insects taken. In Yucatan, pregnant females have been recorded from March to June (Reid, 1997). A large colony in Puerto Viejo contained at least some pregnant females in most months of the year round reproduction. However, a far large percentage were pregnant in May than in later months. (LaVal and Rodriguez-H., 2002). May be found in rural and urban areas.|
