Sheath-Tailed Bats Sac-Winged Bats and Ghost Bats: Emballonuridae - Physical Characteristics, Behavior And Reproduction, Greater Sac-winged Bat (saccopteryx Bilineata): Species Accounts - GEOGRAPHIC RANGE, HABITAT, DIET, EMBALLONURIDS AND PEOPLE, THE FIRS
Emballonurids live in the tropical and subtropical regions of the world, including Mexico, Argentina, Madagascar, and Southeast Asia.
Emballonuridae bats generally live in humid rainforests. These bats tend to roost, rest or settle, in areas that are relatively light compared to what other bat families prefer. Their roosts include the entry areas to caves and other structures, the outside of buildings, hollow trees, and leaves.
Emballonurids eat primarily insects, although they have been seen eating fruit. They generally eat insects while flying, yet some species are known to look for their food along the ground. These bats start foraging, searching for food, relatively early in the day compared to other bats. Some of these bats such as the ghost bats, capture their meals while flying high in the open air. Other bats, such as the proboscis bat, hunt insects above or close to water surfaces.
Because emballonurids prefer roosting in open areas, these bats are among the more common bats for people to spot. They can be seen in trees, on buildings, and at the edges of caves. The social calls they emit are also within human hearing range. Some emballonurids are declining due to human destruction of their natural habitat.
Emballonurids were first recorded in Europe thirty-eight to fifty-four million years ago.
There are several emballonurid species that are endangered or threatened with becoming endangered. The IUCN lists two species as Critically Endangered, facing an extremely high risk of extinction in the wild; two species as Endangered, facing a very high risk of extinction in the wild; and ten species as Vulnerable, facing a high risk of extinction in the wild.

Emballonurids (bats in the family Emballonuridae) are small to medium in size. Their head and body length is about 1.4 to 6.3 inches (36 to 160 millimeters). They can weigh from 0.1 to 3.5 ounces (3 to 100 grams), about the weight of a first-class letter. These bats have thirty to thirty-four teeth. For the most part, emballonurids are brown or gray in color, but this family also includes the whit…
By pulling their hind legs together or apart during flight, the emballonurids can shorten or lengthen their membrane. This gives these bats tremendous control as they steer, maneuver, and turn in flight. Like all bats, they are nocturnal, resting during the day and becoming active at night. During bad weather, some species forage in the afternoon. Some emballonurids roost in large groups, others g…
Physical characteristics: Greater sac-winged bats are relatively small, with a body length of 1.8 to 2.2 inches (47 to 56 millimeters). These bats are also called greater white-lined bats, referring to the two white lines that run down their bodies. Their fur is typically dark brown, while the underside is typically gray. These bats have dark wings, long noses, and the females are slightly larger …
Physical characteristics: Greater dog-faced bats are also referred to as greater dog-like bats. These bats are relatively small, with a head and body length of 2.5 to 2.9 inches (63 to 75 millimeters). Their fur is typically dark or reddish brown and their underside is paler in color. Tufts of hair cover the head. The ears are separated at the base and are usually, along with the wings, black in c…
