The diadem roundleaf bat, Hipposideros diadema, also called the diadem leaf-nosed bat, is one of the most widespread members of its family, found from the Nicobar Islands and Southeast Asia through Indonesia and New Guinea to northern Australia. It is named for its complex horseshoe-shaped nose leaf, and males have a sac behind the nose that secretes a waxy substance thought to attract mates. Adults are six to ten centimetres long, weigh 34 to 50 grams and have a wingspan of 15 to 22 centimetres. It is nocturnal and gregarious, with colonies of two to three thousand, roosting in caves, old mines, sheds and hollow trees. It hunts beetles, moths and grasshoppers by short sallies from a perch, and in the wild lives four to seven years. The IUCN lists it as Least Concern.
