[6] There is a large web of skin between the hind legs (the uropatagium) which may assist in flying and catching insects, although there are no tail bones or calcars to help control it in flight.

[3] In Thailand, it is restricted to a small region of the Tenasserim Hills in Sai Yok District, Kanchanaburi Province, within the drainage basin of the Khwae Noi River.

[3] Since the 2001 discovery of a single individual in Myanmar, at least nine separate sites have been identified in the limestone outcrops of the Dawna and Karen Hills outside the Thanlwin, Ataran, and Gyaing Rivers of Kayin and Mon States.

[9] Despite its restricted geographical range and specialized habitat requirements, Kitti's hog-nosed bat exhibits remarkable genetic diversity within its populations.

Molecular analyses using microsatellite markers have revealed moderate levels of genetic differentiation among cave roosts in Thailand and Myanmar, suggesting historical isolation and limited gene flow between populations.

[10] During this period, the bat forages within fields of cassava and kapok or around the tops of bamboo clumps and teak trees, within one kilometre of the roosting site.

Maternity colonies composed of a small number of females are formed within cave roosts, providing communal protection and thermoregulatory benefits for nursing offspring.

Male mating behaviors, such as courtship vocalizations and scent marking, have been documented in captive populations, indicating potential sexual selection mechanisms.

Kitti's hog-nosed bat is the only extant species in the family Craseonycteridae, which is grouped in the superfamily Rhinolophoidea as a result of molecular testing.

[11][12][7] As a microchiropteran species, Kitti's hog-nosed bat plays a crucial ecological role in its habitat, primarily as an insectivore.

By controlling insect populations, particularly those of agricultural pests and disease vectors, Kitti's hog-nosed bat contributes to ecosystem balance and human well-being.

[10] Currently, the most significant and long-term threat to the Thai population could be the annual burning of forest areas, which is most prevalent during the bat's breeding season.

[3][14] In 2007, Kitti's hog-nosed bat was identified by the Evolutionarily Distinct and Globally Endangered project as one of its Top 10 "focal species".
