Myotis keaysi

Hairy-legged Myotis

Order: Chiroptera
Family: Vespertilionidae

 

Conservation Status: Least Concern.


Myotis keasyi is fairly common in dry lowland forests and common or even abundant in some semi-deciduous or evergreen forests at higher elevations. It roosts in limestone caves and perhaps in hollow trees. Its flight path takes it along forests trails and over streams and clearings, where it is often caught in mist nets. It can be distinguished from similar-looking bats by the hair on its legs and tail membrane below its knees. Only one other bat in its range in the genus Myotis, the Californian Myotis, has a hairy tail membrane, and its fur stops above the knee.
