'Horseshoe bats' (the 'Rhinolophidae' family) are a large family of bats including approximately 130 species grouped in 10 genera. They belong to the suborder Microchiroptera (
microbats).
Families
The Rhinolophidae family is sometimes divided into two families, the Rhinolophidae (horse-shoe bats) and Hipposideridae (Old World leaf-nosed bats). There is little question that these two groups of bats are closely related, but current practise is to classify them as subfamilies (
Hipposiderinae and
Rhinolophinae) in a single family. Many species are extremely difficult to distinguish.
Appearences
All 'rhinolophids' have leaf-like protuberances on their noses. In rhinolophines species, these take the shape of a horseshoe; in hipposiderine, they are leaf- or spear-like. They emit
echolocation calls through these structures, which may serve to focus the sound. Most rhinolophids are dull brown or reddish brown in color. They vary in size from small to moderately large.
Ecology
Rhinolophids inhabit
temperate and
tropical regions of southern
Europe,
Africa, and
Asia south to northern and eastern
Australia, including many
Pacific islands. All species are
insectivorous, capturing insects in flight. Their roost habits are diverse; some species are found in large colonies in
caves, some prefer hollow trees, and others sleep in the open, among the branches of trees. Members of northern populations may
hibernate during the winter; at least one species is
migratory. Like many
Vespertilionidae bats, females of some rhinolophid species mate during the fall and store the
sperm over the winter, conceiving and
gestating young beginning in the spring.
