Otonycteris hemprichii (Peters 1859) Hemprich’s Long-Eared Bat
Hebrew name: אודנן, udnan
Global Threat: NE – Not Evaluated
Regional Threat: VU (B,C) – Vulnerable
Distribution area: Hemprich’s long-eared bat is a desert species found in the Judean Desert, the Negev, and in the Arava down to Eilat.
Historic distribution: Bodenheimer reported the species from the Judean Desert (Nahal Og and Nebi Musa) in the 1950s (in Makin 1977). Makin (1977) reported isolated individuals from Makhtesh Ramon, Mamshit and En Gedi in the 1970s.
Typical Habitat: Roosts in rock crevices (Fenton et al. 1999). Gathers its food off plants, trees and over water. Its diet is composed mainly of beetles and Hymenoptera (Whitaker et al. 1994, Fenton et al. 1999).
Threat and Disturbance Factors: Insecticide use in agricultural areas.
Population Size: Hemprich’s long-eared bat is found over an area of about 6000 km2, usually as isolated individuals. During the breeding season they apparently gather in larger groups made up of several dozen bats.
Fluctuations in Population Size: There seem to have been no fluctuations in population size.
Isolation between Subpopulations: Unknown.
Necessary Steps for Species Preservation:
1. Reducing insecticide use in agriculture.
2. Preserving open water bodies in the desert.
