The Rafinesque’s big-eared bat is an elusive bat with distinctive ears that distinguish them apart from other bats in Florida. The Rafinesque’s big-eared bat weighs between 7 and 13 grams and has gray to brown fur on their back with white fur on their belly.

Roosting Preference: Roosts colonially in small groups – Natural roost sites are known to include hollow trees, tree cavities, and under loose tree bark, but this species has also frequently been found to use abandoned buildings in forests. In Florida, a few colonies have been documented in bridges and bat houses.
