reported in September about conservationists who built an artificial cave in Tennessee in an effort to save bats. At that time more than 5.7 million bats had died from the fungus.

Bats have an important role in regulating insect populations, a function that is vital to successful agriculture. A recent study found that the loss of North American bats could lead to agricultural losses of more than $3.7 billion per year, writes Platt.
The National Wildlife Health Center says bats affected by white-nose syndrome often display abnormal behaviors in their hibernation sites, such as movement toward the mouth of caves and daytime flights during winter. These abnormal behaviors may contribute to the untimely consumption of stored fat reserves causing emaciation.
