Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".
Pipistrellus is a genus of bats in the family Vespertilionidae and subfamily Vespertilioninae. The name of the genus is derived from the Italian word pipistrello, meaning "bat".
The tricolored bat or American perimyotis is a species of microbat native to eastern North America. Formerly known as the eastern pipistrelle, based on the incorrect belief that it was closely related to European Pipistrellus species, the closest known relative of the tricolored bat is now recognized as the canyon bat. Its common name "tricolored bat" derives from the coloration of the hairs on its back, which have three distinct color bands. It is the smallest bat species in the eastern and midwestern US, with individuals weighing only 4.6–7.9 g (0.16–0.28 oz). This species mates in the fall before hibernation, though due to sperm storage, females do not become pregnant until the spring. Young are born helpless, though rapidly develop, flying and foraging for themselves by four weeks old. It has a relatively long lifespan, and can live nearly fifteen years.
The mouse-eared bats or myotises are a diverse and widespread genus (Myotis) of bats within the family Vespertilionidae. The noun "myotis" itself is a Neo-Latin construction, from the Greek "muós and "oûs", literally translating to "mouse-eared".
The fraternal myotis is a species of vesper bat native to East Asia.
Murina is a genus of vesper bats. They are found throughout temperate and tropical regions of Asia.
The pungent pipistrelle is a species of vesper bat in the family Vespertilionidae. It is found in Indonesia and possibly the Philippines.
The Peters's pipistrelle is a species of vesper bat in the family Vespertilionidae. It is found in Indonesia, Malaysia, and the Philippines.
Neoromicia is a genus of vesper bat in the family Vespertilionidae. It contains the following species:
Vespadelus is a genus of Australian bats in the family Vespertilionidae.
Falsistrellus is a genus of vespertilionid family of bats, small predatory flying mammals. They are known from Australia. The poorly researched species have been variously placed by authors, and revised again by studies of their distinct characteristics, consequently the falsistrelles may also be referred to as pipistrelles or false pipstrelles.
Miniopterus, known as the bent-winged or long winged bats, is the sole genus of the family Miniopteridae. They are small flying insectivorous mammals, micro-bats of the order Chiroptera, with wings over twice the length of the body. The genus had been placed in its own subfamily among the vespertilionid bats, as Miniopterinae, but is now classified as its own family.
Laephotis is a genus of bats in the family Vespertilionidae. Species within this genus are:
Nycticeinops is a genus of vesper bat in the family Vespertilionidae. It contains the following species:
Aeorestes is a subgenus of Lasiurus commonly known as the hoary bats.
Laephotis stanleyi, also called Stanley's serotine, is a species of vesper bat in the genus Laephotis. It is found across southern Africa. The species was formerly known as N. cf. melckorum, before being named as a species in 2017.
Lasiurini is a tribe of bats in the family Vespertilionidae. It contains three genera of bats found in the Americas. All three genera were previously considered one genus, Lasiurus, but have since been split from one another. However, the validity of this split is still debated.
Plecotini is a tribe of bats in the family Vespertilionidae. It contains several genera found throughout the Northern Hemisphere, in Eurasia, North Africa, and North America. Several genera in this tribe are known as big-eared bats or long-eared bats. It also contains the spotted bat and barbastelles.
Kozlov's long-eared bat is a species of vesper bat in the family Vespertilionidae. It is found in southern Mongolia and adjacent parts of China.
