Cluster Bat

Myotis sodalis, the Indiana bat or cluster bat, is a medium-sized insectivorous bat in the family Vespertilionidae endemic to the eastern United States. It is one of the most endangered bats in North America, listed as Endangered under the U.S. Endangered Species Act and classified as Near Threatened by the IUCN. The species is named for its behavior of clustering in extremely dense hibernation groups—sometimes thousands of bats per square meter—in specific limestone caves and mines during winter. These few critical hibernacula make the species extremely vulnerable to disturbance and disease. Since 2007, Indiana bats have suffered severe mortality from white-nose syndrome, a fungal disease caused by Pseudogymnoascus destructans that disrupts hibernation and causes mass starvation. During summer, Indiana bats roost under loose bark of dead trees and forage for insects over forested landscapes and riparian areas. Foraging individuals consume moths, beetles, and flying insects. Conservation efforts include cave gate protection, white-nose syndrome research, and summer habitat management on public and private lands across the eastern US.
