Great evening bat

The great evening bat (Ia io) is the largest bat in the vesper bat family (Vespertilionidae) and the only living species in the genus Ia. It is common to Eastern and Southeastern Asia (China, India, Laos, Nepal, Thailand and Vietnam),[1] mainly living in areas with limestone caves at altitudes of 400–1,700 metres (0.25–1.06 mi).[2] Their roost sites have been found both near the cave entrances and up to 1.5 kilometres (0.93 mi) within the cave systems.[3]

The great evening bat reaches a length of 90 to 105 millimetres (3.5–4.1 in). It is colored brown on the top and grayish on the bottom.[4] Average wingspan is .51 m (20 in) and it typically weighs 58 g (2.0 oz).[5]

Not much is known about its habits and behavior. The bat usually lives in small groups. Its food consists of insects, as with most vesper bats. The great evening bat also sometimes feeds on small birds [2]. The bat leaves its sleeping place already in the late afternoon for the search of food. During the winter months it may migrate to warmer regions.

The IUCN lists its conservation status as Least Concern.[1] One of the threats to its survival in South Asia is human influence by habitat destruction; many caves have been turned into attractions. They have also been disturbed by farmers collecting their excrement. Also the excessive use of insecticides poses a threat to the great evening bats.[2]

At four letters, Ia io is tied with Yi qi for the shortest existing (and shortest possible) scientific name of any animal under the International Code of Zoological Nomenclature,[6] and is one of very few scientific names composed solely of vowels [3].

Arielulus

Arielulus is a genus of vesper bats with the following species, sometimes in Pipistrellus:

Genus Arielulus

Collared pipistrelle (A. aureocollaris)

Barbastella

Barbastella is a small genus of vespertilionid bats. There are five described species in this genus.

Birdlike noctule

The birdlike noctule (Nyctalus aviator) is a species of bat. An adult birdlike noctule has a body length of 7.1-9.5 cm, a tail of 5.5-6.4 cm, and a wing length of 5.8-5.95 cm. It nests in the holes in old trees and buildings, and sometimes in mineshafts. It is distributed across Northeast Asia, from northeast China and Siberia through the Korean Peninsula to Japan.

Along with the greater noctule bat and the Asian great evening bat, this is one of three bat species to prey on small, nocturnally-migrating birds, pursuing them in open air. At least one specific bird, Middendorff’s grasshopper warbler (Locustella ochotensis), has been identified based on faecal DNA in the diet of N. aviator in Japan.

Eptesicus

Eptesicus is a genus of bats, commonly called house bats or serotine bats, in the family Vespertilionidae.The 25 species within this genus are:

Little black serotine (Eptesicus andinus)

Greater noctule bat

The greater noctule bat (Nyctalus lasiopterus) is a rare bat found in Europe, West Asia, and North Africa. It is the largest and least studied bat in Europe with a wingspan of up to 46 centimetres (18 in) and is one of the few bat species to feed on passerine birds. Greater noctule bats are the only bat species to hunt birds on the wing rather than when roosting. The greater noctule bat has wings adapted for open-air hunting and uses echolocation frequencies above the hearing range of birds.

Hesperoptenus

Hesperoptenus is a genus of bats within the Vespertilionidae or "Vesper bats" family. Species within this genus are:

Blanford's bat (Hesperoptenus blanfordi)

False serotine bat (Hesperoptenus doriae)

Gaskell's false serotine (Hesperoptenus gaskelli)

Tickell's bat (Hesperoptenus tickelli)

Large false serotine (Hesperoptenus tomesi)

Hypsugo

The genus Hypsugo contains many bats referred to as pipistrelles or pipistrelle bats. They belong to the family Vespertilionidae or vesper bats within the order Chiroptera.

Ia (genus)

Ia is a genus of bat in the family Vespertilionidae. It belongs to the subfamily Vespertilioninae and has been placed in the tribe Vespertilionini. In the past, it has also been considered a synonym or subgenus of the genera Pipistrellus or Eptesicus, which used to contain many more species than they do now. Ia comprises a single living species, the great evening bat (I. io) of eastern and southeastern Asia, and one extinct fossil species, I. lanna, from the Miocene epoch in Thailand. Another living species, I. longimana, was recognized in the past, but it is no longer considered a valid species distinct from the great evening bat.

At two letters, Ia ties the bat-like dinosaur Yi for the shortest possible name of any animal genus under the International Code of Zoological Nomenclature.
