Wall-roosting Mouse-eared Bat, Myotis muricola

The wall-roosting mouse-eared bat (Myotis muricola), also known as the Nepalese whiskered myotis, is a vesper bat that can be found in Afghanistan, Bhutan, Cambodia, Myanmar, and Nepal, among many other areas. It roosts in many areas including folded banana tree leaves, limestone forested areas, artificial caves, hollow trees, and old buildings.  This species was previously classified as a subspecies of Myotis mystacinus, but studies have shown that is a distinct species.

The wall-roosting mouse-eared bat is typically grey to brown in color, with a dark underbelly. Its feet are small, but it has a relatively long tail. As is typical to bat species, the wall-roosting mouse-eared bat is nocturnal and is most active at dawn and dusk. It will feed on insects three times a night, using echolocation to navigate and catch food. Small insects are typically consumed directly, but larger insects must be “slapped” into the mouth with the wing membrane or the tail. Water is consumed from both the insects in its diet or from drips in the bat’s roost. The wall-roosting mouse-eared bat appears on the IUCN Red List with a conservation status of “Least Concern.”
