The Antillean ghost-faced bat (Mormoops blainvillei ) is a species of bat in the family Mormoopidae. It is found in Cuba, the Dominican Republic, Haiti, Jamaica, and Puerto Rico.
These bats range in color from a pale cinnamon to a more reddish color, showing darker pigmentation on the dorsal side as opposed to the ventral. No molting specimens have been observed. Additionally, no geographic variation in color has been studied, observed or documented.
Like other species in the Mormoops genus, the Antillean ghost-faced bat shows elaborate, intricate facial outgrowths and leaflike appendages. The face features nostrils located on a fleshy pad, and coarse bristles protruding from both lips.
The morphology of M. blainvilli is similar to M. megalophylla, as the main adaptations by Mormoops are to reduce body weight to increase flying ability. These adaptations include decreased muscular structures, some of which are absent altogether as compared to species of Phyllostomidae. These restrictions result in a decreased range of extension. The aspect ratio of the wings of one bat were calculated as 6.23, similar to M. megalophylla. These characteristics are hypothesized to give the bat an advantage in terms of flight endurance, and have been adapted for its insectivorous diet.
The Antillean ghost-faced bat has been predominantly observed roosting in deeper, more sheltered caves or abandoned mine shafts, as opposed to caves with multiple entrances. Here, it coexists with other bat species.
Analysis of stomach contents has shown that these bats feed exclusively on insects, which they catch utilizing a pouch formed by the large leaflike tail membrane. Target prey, mostly moths, are caught in midair.
The mating season begins with copulation spanning from January to February. From March to May, pregnancies occur, and the earliest births occur in June. Weaning is completed from August to September, and in October to December, females are non-responsive to mating.
Each reproductive female typically bears one child per year, with twins being reported in only two instances.
