The greater Asiatic yellow bat (Scotophilus heathii) is a species of vesper bat. [2] It is found in Afghanistan, Bangladesh, Cambodia, China, India, Indonesia, Laos, Myanmar, Nepal, Pakistan, Philippines, Sri Lanka, Thailand and Vietnam. [1]
Like many bats, females have delayed ovulation, with the ability to store sperm. This makes them particularly of interest to biologists.[ citation needed ] Studies have shown that seasonal changes in hormones allow them to deposit fat before the onset of winter. [3]
It is named after Josiah Marshall Heath, who presented the type specimen to the Zoological Society of London. [4]
The head and body length of the greater Asiatic yellow bat is 8–9 centimetres (3.1–3.5 in), the forearms measure 6–7 cm (2.4–2.8 in), and the wingspan is40 cm (16 in). The bats weighs 48–52 g (1.7–1.8 oz).
Adults are yellowish bronze brown above and bright yellow to reddish below. Wing membrane is blackish brown. Short and dense fur except on neck. Muzzle is blunt, naked, and dark. Tragus is crescent-shaped and separated from the posterior margin of the pinna by a conspicuous notch. Long tailed. Young are dark grayish brown.
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".
The great evening bat 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, mainly living in areas with limestone caves at altitudes of 400–1,700 metres (0.25–1.06 mi). Their roost sites have been found both near the cave entrances and up to 1.5 kilometres (0.93 mi) within the cave systems.
The least pipistrelle is a species of vesper bat.
The Gobi big brown bat is a species of vesper bat. It is found in Afghanistan, China, India, Mongolia, Pakistan, and Russia. Russian zoologist Professor Count Nikolay Alekseyevich Bobrinski first described it in 1926, the type specimen coming from the Altai Mountains in the Gobi Desert.
The lesser bamboo bat or lesser flat-headed bat is one of the smallest species of vesper bat, and is native to Southeast Asia.
The chocolate wattled bat is a bat in the family Vespertilionidae. It is found only in Australia, including the island Tasmania, and widespread in southern regions. It is known to reside from sea level to at least 1,570 metres (5,150 ft) in Victoria.
Allen's yellow bat is a species of vesper bat. There is some taxonomic debate surrounding this species, with some authors considering Baeodon a genus rather than a subgenus. It is endemic to Mexico.

The lesser Asiatic yellow bat is a species of vesper bat. It is found in Bangladesh, Cambodia, India, Indonesia, Malaysia, Pakistan, the Philippines, Sri Lanka, and Taiwan.
The white-bellied yellow bat or white-bellied house bat, is a species of vesper bat in the genus Scotophilus, the house bats. It can be found in Angola, Benin, Botswana, Burkina Faso, Cameroon, Central African Republic, Chad, Ivory Coast, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Mali, Mauritania, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Sudan, Togo, Uganda, and Zambia. It is found in dry and moist savanna and open woodland. It is a common species with a very wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Schreber's yellow bat or the giant house bat, is a species of vesper bat. It is found in Benin, Democratic Republic of the Congo, Ivory Coast, Ghana, Kenya, Malawi, Mozambique, Nigeria, Senegal, Tanzania, Togo, and Zimbabwe. Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, and moist savanna. It is an uncommon species and its biology is poorly known. It was first described in 1774 by the German naturalist Johann Christian Daniel von Schreber, who named it Vespertilio nigrita. It was later transferred to the genus Scotophilus, making it Scotophilus nigrita.

The lesser short-nosed fruit bat is a species of megabat within the family Pteropodidae. It is a small bat that lives in South Asia and Southeast Asia. It weighs between 21 and 32 grams, and measures 70 to 127 millimetres. It occurs in many types of habitat, but most frequently in disturbed forest, including lower montane forest and tropical lowland rain forest, plus gardens, mangroves, and vegetation on beaches.
