Leach's single leaf bat (Monophyllus redmani), also known as Greater Antillean long-tongued bat, is a species of bat in the family Phyllostomidae. It is found in the southern Bahamas and in all the Greater Antilles (Cuba, Jamaica, Hispaniola (both Haiti and the Dominican Republic), and Puerto Rico). It forms large colonies, with up to a few hundred thousand individuals, and feeds on a relatively wide variety of food items including pollen, nectar, fruit and insects.
