Greater horseshoe bat description

KingdomAnimalia
PhylumChordata
ClassMammalia
OrderChiroptera
FamilyRhinolophidae
GenusRhinolophus

The greater horseshoe bat (Rhinolophus ferrumequinum) is the larger of the two horseshoe bats found in Britain. They are so-named from the horseshoe shaped nose 'leaf', used as part of the bat's echolocation system. The ears are leaf-shaped and have a sharply pointed tip. The fur is thick, and coloured ash-grey above, and buff underneath. Bats are not blind as was once popularly thought. They have good eyesight but rely on their echolocation to navigate and to detect their insect prey. They emit a succession of high-pitched squeaks and judge their position and the location of their prey from the reflected echoes.

Greater horseshoe bat biology

Greater horseshoe bats often roost in buildings during the summer, and their presence can be detected by piles of excrement on the ground. They leave their roosts just after sunset, and during the summer, spend about an hour feeding before returning. They often feed again just before dawn. At the end of August they stay on the wing all night. Greater horseshoe bats mate in autumn, sometimes in late winter or early spring. They form maternity roosts in May and the young are born in mid-July. This species reaches maturity at around three years old and they may live for 30 years. Their preferred food is large beetles, such as cockchafers and dung beetles, large moths and caddis flies. They have been observed watching from a regular roost and then flying out to take passing insects. Greater horseshoe bats hibernate in caves, cellars or disused mines, from late September to mid-May. They may emerge to feed during mild spells.

Greater horseshoe bat status

The greater horseshoe bat is classified as Least Concern (LC) on the IUCN Red List (1). It is classified as Endangered in the UK, listed under Appendix II of the Bonn Convention, Appendix II of the Berne Convention, Annexes II and IV of the EC Habitats Directive, Schedule 2 of the Conservation Regulations 1994 and protected in the UK under Schedule 5 of the Wildlife and Countryside Act (as amended).

IUCN Red List species status – Least Concern

Greater horseshoe bat threats

The greater horseshoe bat has declined by over 90 percent in numbers during the last 100 years. This is due largely to habitat loss, caused by modern intensive farming methods. The destruction of woods, roosting sites, old pastureland, and the use of chemical insecticides, which have seriously reduced the abundance of their insect prey, have all contributed to this decline.

Greater horseshoe bat conservation

This species is listed in the UK Biodiversity Action Plans (UKBAPs), and has been included in English Nature's Species Recovery Programme. It belongs to a family of animals that have been much maligned over the centuries. However, more people are realising just how fascinating bats are, and they receive a high level of legal protection. The main effort in their conservation is to encourage landowners and farmers to manage their land in ways that benefit the bats. They are also being asked to limit the use of ivermectin insecticides, commonly used for treating cattle. The chemical in the insecticide also poisons the cattle's dung, and kills the larvae of dung beetles, one of the greater horseshoe bat's principal foods. As more people learn about bats, it is hoped that the efforts to conserve them as a breeding species will gain more support. They are an intriguing group of mammals, and undeserving of their sinister reputation. The Bat Conservation Trust carries out work on surveys and monitoring, and employs many volunteers.

The UK Biodiversity Action Plan for this species is available at UK BAP.

Glossary

Echolocation
Detecting objects by reflected sound. Used for orientation and detecting and locating prey by bats and cetacea (whales and dolphins).
Larvae
Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
