The Java pipistrelle ( Pipistrellus javanicus ) is a bat in the smooth-nosed family with a wide distribution area in southern Asia . The German and the scientific name refer to the Indonesian island of Java , where the type specimen was found.

features

This bat reaches a total length of 75 to 90 mm, including a 29 to 37 mm long tail and a weight of 4 to 7 g. It has 32 to 37 mm long forearms, 7 to 10 mm long hind feet and 10 to 13 mm long ears. The hair on the top is very dark brown near the root and only slightly lighter in the further course. The fur on the underside is generally lighter with a darker hair base. The narrow tragus in the ear has a rounded tip. Furthermore, the flattened head is characterized by a wide snout. The upper canines have double tips.

Distribution and way of life

The distribution area of the Java pipistrelle extends from the east of Afghanistan along the southern Himalayas to the Southeast Asian mainland and further over the Malay Peninsula and the Indonesian islands to the Philippines and Timor . Separate populations live in central areas of India . The species can be found in the lowlands and in mountains up to 2380 meters above sea level. It lives in diverse forests and in cultural landscapes .

The Java pipistrelle rests in tree hollows, under partially detached tree bark, in rock crevices, in wall crevices or in buildings. The hiding place is often used by a smaller group. The animals start their hunt for flying insects early in the evening. In females there are up to three litters each year, most of which consist of twins. The Java pipistrelle orients itself with the help of echolocation .

status

In a regionally limited area, deforestation and disturbances in the resting place can have a negative impact on the population. The IUCN lists the Java pipistrelle as Least Concern .
