Identification
Bats of the family Megadermatidae (false vampire bats) are distinguished by large ears connected across the forehead, a long, tapering tragus divided into two unequal lobes, a prominent noseleaf, and an interfemoral membrane lacking a bony support connected to the lower leg. The lesser false vampire bat, Megaderma spasma, is a medium-sized bat. Forearm length ranges from 54 to 61 mm, and weight ranges from 20 to 30 g. It possesses a large intermediate noseleaf and raised edges to the posterior noseleaf.
Biology and Ecology
Despite their common name, these bats do not feed on blood, unlike the true vampire bats found in the Americas. Their diet primarily consists of arthropods, but they have also been observed to prey on small, trapped bats. They also consume prey scavenged from tree branches or the ground.
To locate prey, they often rely on sounds emitted by their targets, such as the rustling of dry leaves, the mating calls of crickets, or the echolocation calls of other bats.
Distribution
This bat species is found throughout Southeast Asia. Its distribution is widespread across continents but does not include islands.
Value
This species is rare and possesses scientific research, aesthetic, and natural pest control value by consuming harmful insects.
