Are Indiana bats still endangered?
The Indiana bat (Myotis sodalis) is both a state and federally endangered species. The species was listed in the late 1960s due to human disturbance of caves that bats use for winter hibernating. Indiana bats are vulnerable to these disturbances as they hibernate in large colonies in very few caves.
How many species of bats live in Indiana?
Thirteen bat species have been documented in Indiana. Six species primarily use underground sites such as caves, mines, or tunnels to hibernate in winter. They use caves, trees and/or other structures for summer roosts.
Are bats common in Indiana?
The most common bats in Indiana are the Big Brown, Red and Little Brown. Silver-haired bats migrate through Indiana twice a year. Not all bats live in caves; some hang out under loose or peeling bark, some on limbs of trees, and a few prefer to hang out in buildings (and your attic).
Are bat populations declining?
Research on bat populations in North America reveals how much they are declining in areas impacted by white-nose syndrome. The fungal disease has destroyed entire populations of bats in the United States and Canada.
What would happen if the Indiana bat went extinct?
One bat can eat between 600 to 1,000 mosquitoes and other flying pests in just one hour! If bats disappear the insect population will boom, causing crop failure, economic damage and human illness.
What kills the bat population?
White-nose syndrome has killed over 90% of northern long-eared, little brown and tri-colored bat populations in fewer than 10 years, according to a new study published in Conservation Biology.
Why are there no bats this year?
This is largely due to the result of human activity including habitat destruction, pesticide use, climate change, wind turbines, and general fear. Bats seek shelter under peeling bark on dead trees.
When was Indiana bat listed as endangered?
The species was originally listed as in danger of extinction under the Endangered Species Preservation Act of 1966 and is currently listed as endangered under the Endangered Species Act of 1973, as amended. The scientific name of the Indiana bat is Myotis sodalis.
What are bats natural enemy?
Bats have few natural predators — disease is one of the biggest threats. Owls, hawks and snakes eat bats, but that’s nothing compared to the millions of bats dying from white-nose syndrome.
What is the life expectancy of a bat?
The average bat lifespan is up to 30 years in the wild. Although most bat species don’t make it past 20 years, six species have been verified by scientists to live for more than 30 years. A small bat from Siberia set the world record in 2006, living for 41 years.
What eats the Indiana bat?
Predators of Indiana bats include snakes, owls, and raccoons. Indiana bats are insectivores that prey on beetles, flies, moths, and other flying invertebrates. To locate their prey, most insect-eating bats use a system called echolocation, which is similar to sonar used in ships.
What are bats lifespan?
The longest-living bat is 41 years old. Although most bats live less than 20 years in the wild, scientists have documented six species that life more than 30 years. In 2006, a tiny bat from Siberia set the world record at 41 years . The Townsend’s big-eared bat’s average lifespan is 16 years.

Based on a 1985 census of hibernating bats, the Indiana bat population is estimated around 244,000. About 23% of these bats hibernate in caves in Indiana.
What are the limiting factors for the Indiana bat population?
The Indiana bat is a long-lived species with low fecundity, and as such, the fundamental limiting factors to population viability are number of years over which individual bats are able to produce offspring and the survival of pups to reproductive age.
Why is the Indiana bat endangered?
