Unusually for lasiurine bats, only the front half of the tail membrane is furred, and this species also lacks white markings on the shoulders and wrists.

[2] This species typically inhabits wooded areas near permanent water sources or coastal habitats with Spanish moss (Tillandsia usneoides) or palm trees.

One study found bats favored Sand live oaks (Quercus geminata) with an average roost height of 2.23 m above the ground and 1.57 m above the nearest vegetation.

[4] Mating occurs during flight in the fall (and occasionally winter), and although females may have three or four embryos in the spring, typically only twins are born in late May or early June.

[2] This species is not affected by white-nose syndrome, although the causative fungal agent, Pseudogymnoascus destructans has recently been found within their range.
