It occurs in moist, evergreen lowland rainforests in the Narathiwat Province of southern Thailand.It has only been encountered in the Bala Forest of Hala-Bala Wildlife Sanctuary.
It eats insects, foraging for them only 2–3 m (6.6–9.8 ft) above the forest floor. It likely roosts in leaves or hollow trees.
It is currently evaluated as critically endangered by the IUCN.It meets the criteria for this evaluation because its area of occupancy and extent of occurrence are both very small, at less than 4 km2 (1.5 sq mi).Also, there is a projected decline in the quality and extent of their habitat.It is threatened by habitat loss due to deforestation and the expansion of agriculture.
