Savi's pipistrelle
Savi's pipistrelle (Hypsugo savii sometimes classified as Pipistrellus savii) is a species of vesper bat found across North West Africa, the Mediterranean region and the Middle East. It feeds at night on flying insects. In the summer it roosts under bark, in holes in trees, in old buildings and in rock crevices but in winter it prefers roosts where the temperature is more even such as caves, underground vaults and deep rock cracks.
Description
Savi's pipistrelle is a small species of bat with a head and body length of between 1.75 and 2 inches (44 and 51 mm) and a forearm (elbow to wrist) length between 1.25 and 1.5 inches (32 and 38 mm). It weighs between 0.26 and 0.35 ounces (7.4 and 9.9 g). It has broad, rounded ears each with a short tragus that is widest in the middle and narrows towards the rounded tip. The face, ears and wing membranes are black. The short fur on the upperside of the head and body is dark brown and that on the underside is pale, with the chin, throat and chest contrasting sharply with the animal's back. The tail is rounded and is rather longer than is the case in other closely related species.
