These bats live in trees in wooded areas and roost up in the foliage curled up in their furry tail membrane. They are mainly solitary, just getting together to mate and during migration. They eat lots of moths as well as other insects. They live throughout the eastern half of the country. In fall the more northern ones migrate to southern areas, often using the same migratory routes along the eastern seaboard as some birds do.
We were so lucky to see it!
