False Vampire Bat Extra Quality
Megadermatidae, or false vampire bats, are a family of bats found from central Africa, eastwards through southern Asia, and into Australia. They are relatively large bats, ranging from 6.5 cm to 14 cm in head-body length. They have large eyes, very large ears and a prominent nose-leaf. They have a wide membrane between the hind legs, or uropatagium, but no tail. Many species are a drab brown in color, but some are white, bluish-grey or even olive-green, helping to camouflage them against their preferred roosting environments. They are primarily insectivorous, but will also eat a wide range of small vertebrates.
false vampire bat
These species are collectively called false vampire due to the old misconception that they were sanguivorous like the true vampire bats.The ghost bat, heart-nosed bat, lesser false vampire bat, and greater false vampire bat feed on insects and small vertebrates; the yellow-winged bat and Thongaree's disc-nosed bat are likely fully insectivorous.The heart-nosed bat, greater false vampire bat, and the ghost bat are three of the few bat-eating bats in the world.All species of this family are nocturnal, with the exception of the yellow-winged bat which is sometimes active in daylight.
There is confusion about the relationship of species within Megadermatidae.A 2015 study concluded that, while they did not have enough genetic data to fully resolve these relationships, the two Megaderma species should be in separate genera.The authors of the 2015 paper suggested that the greater false vampire bat, Megaderma lyra, should be renamed as Lyroderma lyra.The recovered cladogram in the 2015 study had relatively low posterior probabilities, however, underscoring the need for future study to achieve higher resolution.Note that Thongaree's disc-nosed bat, Eudiscoderma thongareeae, was not included in this analysis, as it was not described as a new species until 2015.
The greater false vampire bat (Lyroderma lyra) is a species of bat in the family Megadermatidae, the false vampire bats. It is native to Asia. It is also known as the Indian false vampire bat or greater false-vampire
Megadermatids are medium-sized to large bats with a head and body length of 6.5 to 14.0 cm. These "false vampires" or yellow-winged bats are quite distinctive in appearance, with long, erect noseleaves (fleshy protrusion from the nose) and huge ears. Echolocation calls are made through the nose, and the large noseleaf focuses the sound, acting like a megaphone. Megadermatid ears also have a fleshy protrusion called a tragus. The tragus is divided in this family, and the ears are joined at the base by a band of skin across the forehead. There is an extensive tail membrane ( uropatagium), but the tail itself is short or absent.

In this particular training session, Tuttle was recording the bats’ echolocation sounds.An African heart-nosed bat pup clings to its mother as she flies. Female bats of this species have ”false nipples” (below) that a pup can grip while in flight, allowing it to hang onto its mother’s neck. The mother’s actual mammary glands are on her chest (one can be seen here as a small round spot in the fur). The African heart-nosed bat can hear the footsteps of a beetle walking on sand from a distance of more than six feet.
Diet:The lesser false vampire bats are insectivorous and their main diet consists of grasshoppers and moths. Occasionally they also eat small vertebrates including other bats. They are nocturnal and start foraging at dawn.
Megaderma spasma (Lesser False Vampire Bat) is a species of bats in the family false vampire bats. They are native to Asia. They are nocturnal carnivores. Reproduction is viviparous. They rely on flight to move around.
Unlike other species of bats, vampire bats can walk, run, and jump, which helps them attach to their prey. Heat sensors on their noses help them find a good spot on an animal's body to feed. And strong hind legs and a special thumb help them take off after feeding.
The literature suggests that in familiar laboratory settings, Indian false vampire bats (Megaderma lyra, family Megadermatidae) locate terrestrial prey with and without emitting echolocation calls in the dark and cease echolocating when simulated moonlit conditions presumably allow the use of vision. More recent laboratory-based research suggests that M. lyra uses echolocation throughout attacks but at emission rates much lower than those of other gleaning bats. We present data from wild-caught bats hunting for and capturing prey in unfamiliar conditions mimicking natural situations. By varying light level and substrate complexity we demonstrated that hunting M. lyra always emit echolocation calls and that emission patterns are the same regardless of light/substrate condition and similar to those of other wild-caught gleaning bats. Therefore, echoic information appears necessary for this species when hunting in unfamiliar situations, while, in the context of past research, echolocation may be supplanted by vision, spatial memory or both in familiar spaces.

The false vampire bats (Megaderma) are a subfamliy of bats. They are two species that occur in Asia. There are two living species, the lesser tailed vampire bat (Megaderma spasma) and the greater tailed vampire bat (Megaderma lyra) . They are unrelated to the vampire bats (which only occur in South America). Unlike the vampire bats, they also do not feed on blood, but are insectivores. They are also unrelated to the spectral bat (which is called Vampyrum, but which is an omnivore)
Among microbats, the largest species is actually pretty big: the false vampire, or spectral bat (Vampyrum spectrum), weighs 5 to 6.7 ounces (145 to 190 g) and has a wingspan of up to 40 inches (1 m). The smallest bat of them all is the bumblebee bat (Craseonycteridae thonglongyai), according to the University of Michigan Museum of Zoology. This tiny furrball-with-wings grows to only about 1.25 inches long (3 cm) and weighs about 2 grams (0.07 ounces).
It's the countdown to Halloween, a time when bats are often falsely portrayed as terrifying bloodsucking fiends. This Halloween let's celebrate these amazing creatures as they really are - gentle, intelligent mammals that desperately need our help to survive! Here are some ways that you can get batty this Halloween...
Vampire bats do exist - there are three species, all found in Central and South America. But they are nothing like the enormous, blood-crazed monsters portrayed in horror fiction! About the same size as the UK's noctule bat, vampire bats feed mainly on the blood of cattle and other livestock. They make a small graze on their host's skin to encourage a flow of blood, then lap it up with their tongues, consuming about a tablespoon of blood each night. An anti-coagulant in their saliva stops the blood of their host from clotting - a gruesome fact, until you discover that the anti-coagulant has been used to develop a treatment for stroke patients! There are even some species of false 'vampire bats', so-called because they were originally thought to feed on blood. One such species is the ghost bat, Australia's only carnivorous bat. This pale-coloured bat feeds on small animals (including other bats) and has great spiritual significance to the Australian Aborigines. Another appropriately-named bat for this time of year is the little goblin bat, which can be found across Africa, South America and Australia.
- There are over 1000 species of bats and only three of these are vampires.- There are no Vampires in Transylvania - they live in South and Central America.- Bats fly and feed in the dark, which they are able to do by producing a stream of high-pitched calls and listening to the returning echoes which give a distinct 'sound' picture of the surroundings. This is called 'echolocation'- Bats in the UK eat only insects, which they catch in flight or pick off water, foliage or the ground. In the summer a pipistrelle bat can eat 3,000 insects a night! When there are few insects, bats hibernate in cool parts of buildings, caves or hollow trees.- Other than the plastic bats in shop windows you are unlikely to see any bats flying around at this time of year as bats will be looking for suitable sites to hibernate for the winter ahead.- Bats are long-lived (some can live for up to 30 years). They are warm-blooded, give birth and suckle their young. They are very sociable animals, living together in colonies.- All 18 species of bats in the UK are under threat from loss of habitat and declines in insect numbers.
