Buffy flower bats live in subtropical and tropical forests, including pine woodlands. Their roosts are located in hot caves, where temperatures can range from 25 to 28 degrees Celsius (Soto-Centeno and Kurta, 2003). Roosts have been found to contain a few hundred to a few thousand individuals. These bats hang alone or bunched from cave walls and ceilings. Buffy flower bats have been found both in the inside portions of the hot caves where it is dark, as well as exterior where there is more light. Buffy flower bats tend to choose hot caves with only slight climate changes. It is thought that buffy flower bats may visit numerous caves throughout their home range (Goodwin, 1970). These animals have been detected from low to medium levels of elevation; they have been captured in dry washes from sea level to 100 meters elevation (Baker et al., 1978). (Baker, et al., 1978; Goodwin, 1970; Soto-Centeno and Kurta, 2003)
Buffy flower bats are medium-sized bats with a head and body length of 65 to 75 mm, and a tail length of 12 to 17 mm. They have a forearm length of 45 to 55 mm and weigh about 16 to 18 g. The upper body is a yellowish brown or buffy color, and lower body is a paler brown color. These animals have bicolored dorsal hairs, which are colorless near the body with the ends tipped a chestnut brown. The head and face is a paler brown color than the rest of the body, with the hairs shorter and unicolored. They have a long narrow nose with a small, but prominent notched noseleaf, which lies on a hairless nasal pad. They have simple ears that are about as broad as they are long. These ears include a tragus with notched edges. The lower lip of buffy flower bats has a split down the middle. They have a long, protractible tongue covered in papillae. The short tail projects past the interfemoral membrane. They have a calcar, helping distinguish them from other, similar species. The skull is defined by a well developed and complete zygomatic arch. The lower molars are cuspidate and include a distinct cutting edge. The dental formula is 2/2, 1/1, 2/2, 3/3, making a total of 32 teeth. They have an elongated rostrum with the nasal region being concave. Bats that live in hot caves, such as buffy flower bats, tend to have lower basal metabolic rate than other related species living in different environments. Two subspecies of (Baker, et al., 1978)are recognized.
The mating system of buffy flower bats is most likely harem-polygyny. Single males are found with groups of females in roosts.
Buffy flower bats have one estrous cycle per year. The breeding season is restricted to between February and June. Most prenatal development takes place during the first months of the year, with parturition occurring in the early summer (Baker et. al.,1978). Females trapped in early and late February were found to bear small embryos, and females with well developed fetuses were trapped in April and May. Birth occurs in May and June. Females gather in maternity colonies to raise their young. The young start approaching adult size near August (Baker et. al., 1978). Like most bats, buffly flower bats bear a single offspring each year. (Baker, et al., 1978; Soto-Centeno and Kurta, 2003)
Buffy flower bat newborns are born with their eyes open and ears partially erect. They are born naked, although most related phyllostomids possess fur at birth. The newborns have also been recorded to be smaller at birth than other phyllostomids. The small size of neonates is linked to the use of hot caves and lower basal metabolic rates, which slows the rate of development of embryos (Soto- Centeno and Kurta, 2003). Average body mass for newborn buffy flower bats is 4.6 g. They have an average forearm length of 24.0 mm. Newborns are about 23 to 25 percent of the maternal mass and about 44 to 48 percent of the mother’s length (Soto-Centeno and Kurta, 2003). At birth, neonates have pinkish skin and translucent patagia. They are dark brown under the skin on the head and dorsal part of the body. The canine teeth have already erupted at birth (Soto-Centeno and Kurta, 2003). After the young are born the mother licks the young clean and cuts through the umbilical cord. Females nurse their young until they reach independence, within about 2 months after birth. (Baker, et al., 1978; Soto-Centeno and Kurta, 2003)
Little is known about the lifespan of buffy flower bats, but many phyllostomids regularly live to 10 years in the wild.
Buffy flower bat flight is described as straight with slow and deliberate wingbeats (Goodwin, 1970). Females travel between islands to form maternity roosts. These bats are nocturnal and feed at night. Buffy flower bats are highly intolerant of human interaction and disturbance of their habitat and will not continue to live in a cave that has been visited by humans. Buffy flower bats live in colonial roosts of a few hundred to a few thousand individuals. (Goodwin, 1970)
Little is known about the home range of.
Little is known about the communication and perception of buffy flower bats. They use echolocation to navigate at night. Given their food preferences, they are likely to use olfaction to find and identify nectar and fruit sources. Most mammals use chemical cues in communication.
Predators of buffy flower bats have not been reported. They are likely to be preyed on by nocturnal raptors, such as owls and climbing snakes, as are most bats. They roost in inaccessible places, are active at night, and are cryptically colored, reducing their overall risk of predation.
Many plants rely on these bats to pollinate them such as agave, prickly-pear cacti, other cacti, wild calabash, and night-blooming jasmine. Nine species of ectoparasites are found on . There are no known endoparasites. (Baker, et al., 1978)
Buffy flower bats provide important ecosystem services through pollination. Humans benefit directly from their pollination of important food plants.
There are no known adverse effects of buffy flower bats on humans.
Buffy flower bats are currently regarded as threatened, but habitat loss and roost disturbance are immediate concerns. Habitat loss may be a result of rising sea level and flooding of their roosts.

uses smells or other chemicals to communicate
used loosely to describe any group of organisms living together or in close proximity to each other - for example nesting shorebirds that live in large colonies. More specifically refers to a group of organisms in which members act as specialized subunits (a continuous, modular society) - as in clonal organisms.
