Serotine

Eptesicus serotinus (Schreber 1774) Serotine
Hebrew name: אפלול מצוי, aflul matzuy

Order: Chiroptera
Family: Vespertilionidae

Global Threat: NE – Not Evaluated
Regional Threat: EN (A4a,B,C) – Endangered

Distribution area: A lone individual was found in a cave near Bet Shemesh in the 1990s and in 2000. All other observations are from the fringes of the Hula Valley, from Mt. Hermon and from one cave in the Upper Galilee. The colony in Nahal Ammud disappeared during the 1960s.

Historic distribution: Bodenheimer (1958) reported the species from Jerusalem and Tel Aviv (in Makin 1977). Harrison (1961-2) reported a breeding colony in Nahal Ammud (in Makin 1977). The species was not found in the survey carried out in the 1970s (Makin 1977).

Typical Habitat: Inhabits deep caves. In Europe it is found in houses and forages in woodlands, meadows and along hedges (Macdonald & Barrett 1993).

Threat and Disturbance Factors:
1. Insecticide use in agricultural areas.
2. Human visitors to roosting and wintering caves.

Factors that led to population decline in the past:
1. In the 1940s and 1950s: bat collection by scientists.
2. From the 1960s to the mid-80s: poisoning by activity to eliminate fruit bats in shared caves.

Population Size: The population in Israel is very small. The only known colony has less than 200 bats. The species is distributed over an estimated 1000 km2.

Fluctuations in Population Size: The population decreased drastically during the 1950s and 1960s. Isolated individuals may possibly be found over a larger area.

Isolation between Subpopulations: Unknown.

Necessary Steps for Species Preservation:
1. Protecting roosting and breeding caves.
2. Reducing insecticide use in agriculture.
