What species of bats are affected by White-nose Syndrome?

White-nose Syndrome mostly affects hibernating bats. More than half of the 47 bat species living in the United States and Canada hibernate to survive the winter.

Twelve bat species, including two endangered species and one threatened species, have been confirmed with white-nose syndrome in North America. The causative fungus, Pseudogymnoascus destructans (Pd), has been found on an additional six species, including two endangered species, without confirmation of the disease.
