The largest bat is the flying fox (Pteropus giganteus), an Old World bat found on tropical islands from Sri Lanka east. A large adult weighs about 1.2 kilograms, with a wingspan of almost 2 meters (about 6 feet). It eats fruit and is harmless to people, but its importation into the United States is forbidden because of the damage it might do to fruit tree crops.
