Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2017
Date Assessed: 2016-08-29
Assessor(s): Arroyo-Cabrales, J. & Álvarez-Castañeda, S.T.
Reviewer(s): Solari, S.
This species is listed as Least Concern in because of its wide distribution (although it seem uncommon), occurrence in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Hibernates in caves for periods of 5 months, starting at the end of November to the beginning of April (Ceballos and Oliva 2005). These small bats are typically found in conifer forests and other habitats that receive moderate moisture (Holloway and Barclay 2001). This species feeds on a variety of small flying insects. Prey includes moths, flies, beetles, and bugs. Foraging flight is slow and maneuverable; this small bat is often seen foraging among trees and over water.

Threats [top]

Major Threat(s): There are no major threats throughout the species' geographic range.

Conservation Actions [top]

Conservation Actions: Inside its wide range it is possible to find several protected areas where its populations are relatively secure. Until recently, it has been listed under M. ciliolabrum, and therefore some basic ecological information may not properly pertain to this species. This distinction should be assessed to have a clear understanding of its populations and threats.
