Order : CHIROPTERA
Family : Vespertilionidae
Species : Myotis muricola

Forearm Length : up to 3.8 cm
Weight : up to 5.5 grams

The Whiskered Myotis is a small, insectivorous bat occurring in forested and cultivated areas.  It is well known for roosting by day in young, rolled-up banana leaves. In Thailand large colonies also reportedly roost in caves.

It may be observed flying up and down forest trails, in a linear flight path with stiff wingbeats. The species may also hawk small insects around street lights in suburban areas.

The fur is dark brown to dark grey on the upperside, and medium to pale grey underneath.  The wing membrane extends to the base of the toes, and almost fully encloses the tail. The ears are moderately long and pointed, the eyes are small, and the snout is blunt.

The species gets its name from the fine, sensory hairs which protrude from the snout - these can be clearly seen in the close-up in Figure 2.

The species ranges from eastern India through Burma, Thailand and Indochina to Peninsular Malaysia, Singapore, and most of Indonesia and the Philippines. It is locally common in many parts of its range.


Figs 1 and 2 : This bat was found clinging to a banana leaf by day. The whiskers can clearly seen extending from the snout.

Fig 3 : Another example from Singapore, flying out of its roost at dusk.

Fig 6 : This example, from coastal, agricultural habitat in Lombok, Indonesia, has golden frosting to the tips of its fur on the throat and belly.
