Least pipistrelles ( (Francis, et al., 2010)) are found throughout south and southeast Asia, from Afghanistan to China. THey are also found in India, Nepal, Pakistan, Sri Lanka, Borneo, the Philippines, Vietnam, Laos, and Indonesia.
Least Pipistrelles are found in a variety of habitats including forests, rural areas and urban areas. They inhabit secondary hill, montane or montane mossy forests in southeast Asia, in zones ranging from arid to humid. They roost in trees, leafy canopies, and in the walls or ceilings of buildings. They have been observed at elevations ranging from 800 to 1700 m above sea level. (Francis, et al., 2010)
bat, ranging in length from 69 to 77 mm in length and ranging in mass from 3.2 to 4.2 g. It has dark brown fur, transitioning to paler fur on the venter. It has a broad muzzle and the ear and tragus are relatively short when compared to other species in this genus. Sexual dimorphism has not been reported in this species. (Francis, et al., 2010)is a very small
There is no information available regarding the mating system of Pipestrellus pipestrellus, is known to form maternity roosts, with breeding males defending territories. Courtship in P. pipistrellus includes specific flight patterns and olfactory cues, including pheromones produced by males. A trait common to bats in the family Vespertilionidae is delayed fertilization, which allows the female to postpone fertilization until well after mating, thus allowing births to be precisely timed to occur when resources are plentiful. ("Vesper Bats", 2011; Francis, et al., 2010; Russ, et al., 2005). Two separate breeding seasons exist for this species: one which occurs during February and March, and the other which occurs during July and August. These breeding seasons generally produce between one and three offspring. A close relative of ,
There is limited information available regarding the reproductive behavior of Pipistrellus subflavus has a gestational period that lasts 44 days. Pipistrellus subflavus pups have an average birth weight of 1.8 g and are weaned by 4 weeks of age and become independent between 4 and 5 weeks of age. Pipistrellus subflavus reaches sexual maturity between 3 and 11 months of age. (Fujita and Kunz, 1984; Hoying and Kunz, 1998). It breeds for two months at a time, twice a year from February to March and from July to August. Number of offspring per breeding cycle ranges from 1 to 3 pups, with an average of 2. The closely related

The average home range size of genus demonstrate considerable variation in home range size. For example, Pipistrellus pipistrellus has an observed home range of 1,526 ha, while P. pygmaeus has an average home range size of 487 ha. Both species change roost sites on a regular basis. (Nicholls and Racey, 2006)is unknown. However, other members of this

In addition, Pipistrellus pygmaeus exhibits distress through vocal signals. perceives its immediate environment via echolocation and olfactory cues. In general, bats have reduced vision.

As an insectivore,likely helps controls insect pest populations throughout its geographic range. Parasites of this species have not been documented.
As an insectivore,helps controls insect pest populations, which likely helps reduce insect induced crop damage and disease transmission rates from insects to humans.
In urban and suburban settings,is known to roost in the walls and ceilings of buildings. As a result, this species can cause a great deal of damage to the buildings it roosts in.
