Three subspecies of Brachyphylla cavernarum are recognized. Brachyphylla cavernarum cavernarum is the largest of the subspecies and occurs from St. Croix to St. Vincent. Brachyphylla cavernarum intermedia is of intermediate size and occurs in Puerto Rico and the Virgin Islands with the exception of St. Croix. Brachyphylla cavernarum minor occurs in Barbados and is characterized by its small size.[2]
The Antillean Fruit-eating Bat has white to yellow-white hair at the base with darker coloration in the dorsum. Mature individuals measure from 65 to 118 millimeters (2½ to 4⅝ inches) with a forearm length ranges of 51 to 69 millimeters (2 to 2¾ inches) in length. The average weight is 45 grams (1⅝ ounces).[3]
The Antillean Fruit-eating Bat occurs in Puerto Rico, the Virgin Islands and the Lesser Antilles up to St. Vincent and Barbados. Individuals roost in a variety of settings which include unused buildings, caves, dense tree tops, crevices, large wells, and cliffs. Sites without direct sunlight are preferred by the species although large colonies have been found in sunlit areas. The species occurs in dry arborescent vegetation on St. John.[2]
The Antillean Fruit-eating Bat has a varied diet which includes fruits, pollen, nectar, and insects. Fruits consumed in the wild include papaya, mango, Indian almond, manjack (Cordia spp.), royal palm, and sapodilla. In captivity the species has been observed consuming bananas, apples, pears, melons, peaches, and the flowers of the Kapok, sausage tree, royal palm, portia tree, and Jatobá. Confirmed insects consumed include one mite species (Macronyssidae), two batfly species (Streblidae), one tick species (Argasidae), and two bat-mite species (Labidocarpidae). These bats feed in the canopy of the forest and in the ground.[2]
The Antillean Fruit-eating Bat move out from the roost synchronically one hour after sunset and 20 minutes after the Jamaican fruit bat (Artibeus jamaicensis). This synchronization is also evident when returning to the roosts which happens just before the break of dawn.[2]
