Bulmer's fruit bat is a cave-dweller that occurs in mid-montane forests. It has been found living in a cave at 2300 m elevation. Its altitudinal range is at least 1800 – 2400 m. Bulmer's fruit bat was first described from 12,000-year-old fossils found in the central highlands in
Chimbu Province, Papua New Guinea in 1960. It may have become extinct there about 9000 years ago. In 1975, it was discovered in the
Hindenburg Wall area of
Western Province, Papua New Guinea, in a cave known as Luplupwintem. At that time, local inhabitants described the bat as being abundant, perhaps numbering thousands of bats. However, two years later, the colony had been decimated, apparently by hunters who entered the cave with shotguns and store-bought ropes. During the 1980s, no bats were seen and it was feared that the species may have become
extinct. ==Ecology==
