This medium-sized bat is predominantly black (including the wings, ears, interfemoral membrane, and fur) with white-tipped hairs.

This forest inhabitant is known to occur from southeastern Alaska in summer to northeastern Mexico in winter [5] and is found in arid habitats at low elevations during seasonal migrations.

Gestation typically takes 50–60 days, so that parturition of pups occurs in early summer when insect availability is high.

[8] Pups are born breech by presentation, and the mother consumes the placenta [9] Females typically give birth to two offspring, with an even sex ratio.

Silver-haired bats consume primarily soft-bodied insects, such as moths, but will also take spiders and harvestmen.
