The tricolored bat (previously known as the eastern pipistrelle) is one of the smallest in North America with a short face and large eyes and ears. Its fur is a yellowish-brown color. This species prefers open woodlands and woodland edges, especially areas near water. Maternity roosts form in dead or live foliage, while caves, mines, and other rock crevices are often used for summer roosts and winter hibernation. Tricolored bats prey upon flying insects, such as moths, mosquitoes, and ants. The species has suffered rapid population declines due to white-nose syndrome.
The tricolored bat can be found from southeast Canada through to the eastern United States and into east Mexico to Honduras
