features

With a head-torso length of 72 to 78 mm, a forearm length of 50 to 60 mm and a tail length of 50 to 62 mm, the harlequin bat is one of the medium-sized smooth noses. The species has a brightly colored coat when compared to other family members. The basic color is red-brown on the top and dark brown on the belly. There are often several white spots on the head and back near the flight membrane . In addition, many individuals have a white neck collar, white stripes on the underside along the flight membrane or a white eel line on the top. This color is a camouflage , as the animals can be mistaken for fruit or rolled up leaves.

The triangular ears are medium in size and rounded. The orange-brown bones of the arms and fingers contrast with the dark gray-brown flight skin. The harlequin bat has only one pair of upper incisors, which are quite large. Your tooth formula is 1/3 1/1 1/2 3/3.

Distribution and way of life

The distribution area extends from the east of Nepal via Bhutan , northeast India , Bangladesh and Myanmar to southeast China , Thailand , Laos and Vietnam . Scotomanes ornatus is also found on Hainan . This bat can be found in the lowlands and in mountains up to 2200 meters above sea level. It is often seen in the forest-covered hill country and in damp valleys.

The individuals rest mainly in the thick undergrowth and rarely in caves. They often leave their hiding spots well after dusk and mainly hunt insects.
