It is the sole species of its genus and is closely related to Van Gelder's bat (Bauerus dubiaquercus), which is sometimes included in Antrozous.

[6] The bacula of pallid bats are wedge or spade-shaped, generally with a short narrow base which widens and then tapers towards the tip.

During the day time, pallid bats typically roost in cracks and crevices, which may include tile roofs, exfoliating bark of trees, or rocky outcrops.

[1] Pallid bats are insectivores that feed on arthropods such as crickets, and are capable of consuming up to half their weight in insect every night.

Pallid bats were found to have one or more missense mutations that substitute amino acids in their voltage-gated sodium channels, which may be responsible for their resistance to scorpion venom.

Male bats store sperm in the spring and summer, a process driven by changes in melatonin as a response to decreasing daylight hours.

The rise of anthropogenic noise pollution, such as traffic, in their habitats is negatively impacting their foraging and can reduce efficiency by up to three times.

[19] Pallid bats have been identified in the fossil record from late Pleistocene deposits in the western United States and Cuba.
