In the spring and summer, it can be found in the Great Lakes region and the Great Plains region.


Eastern red bats are insectivorous. They mainly eat moths. But, they also eat other insects. They eat many pests, like gypsy moths, tent caterpillar moths, Cydia moths, Acrobasis moths, cutworm moths, and coneworm moths.


Eastern red bat breeding season starts in the autumn. Many males can mate with one female. Pups are born in the summer. Eastern red bats usually give birth to three pups.

Even after the pups have learned how to fly, they stay with their mother for a short time before staying by themselves.
