The eastern bat has light gray-brown fur on the upper side of its body and more whitish fur on the under side, with an orange-red face. Females are more likely to exhibit paler coloring. This species prefers to live within more remote, forested areas. Males are more likely to occur in cooler regions, with females tending to occur in warmer, lowland areas. This bat will roost amongst the foliage of deciduous or occasionally evergreen trees. In winter, this species hibernates by burrowing into leaf litter and bunch grass. Their diet consists primarily of moths but other insects such as beetles and members of Hemiptera are also featured on the menu. Females commonly have more than a single pup (baby bat), twins or triplets, but can have liters of up to five pups.
