Large-eared Horseshoe Bats emit their echolocation calls though their noses and appear to use their noseleaf to direct the calls. They fly like butterflies, hovering and darting quickly after their prey.
Large-eared Horseshoe Bats roost in caves and old mines that are warm and humid. They don't roost together in large colonies, though they are found roosting with Eastern Horseshoe Bats. These bats hang from the cave ceiling rather than on the walls like other microbats.
Feeding and diet
Large-eared Horseshoe Bats eat moths and other insects. They fly close to the ground in thick forest and catch their prey on or close to the ground.
Large-eared Horseshoe Bats are vulnerable to disturbance from human visitors to cave roosts, destruction of caves by mining, and loss of feeding habitat by clearing and land degradation from agriculture.
