This amount of fat amounts to 29.3% of the live mass at the beginning of hibernation. They are active at night and occasionally at dawn and dusk. Thus, visits to caves in which there are hibernating bats should be avoided to minimize the risk of causing unnecessary arousals and threatening the survival of the bats.

The echo and emission spectrograms are distinguished by the time that elapses between sound emission and an echo at each frequency in the FM sweep. Feeding activity is often interrupted by periods of night roosting, where individuals seek temporary shelter alone or in small groups in open buildings, on the rafters of porches, carports, and breezeways.
