Georgia’s records for this bat cluster around the Piedmont’s granite country near Atlanta, the exposed rock domes of Stone Mountain and Panola Mountain and the river corridor of Chattahoochee River National Recreation Area, a mix of rock crevices to roost in and open water to drink from and hunt insects over. NatureServe ranks the species S5, secure, in Georgia, and it’s recorded here often enough to be one of the state’s more commonly reported bats.

It hunts alone after dark, chasing down beetles and other flying insects over water and open ground, and can live surprisingly long for its size, up to 19 years in the wild. By day it roosts in rock crevices, tree hollows, and buildings, which makes it one of the bat species Georgians are most likely to find sharing an attic or barn.

Reports peak in April and May, matching the weeks when bats are emerging from winter torpor and females are gathering into maternity roosts to raise pups. Records continue at a lower level through the rest of the year, consistent with a true year-round Georgia resident rather than a seasonal visitor.
