Species details: 

A smaller and lighter version of M. myotis, the Lesser Mouse-eared bat has a narrow, pointed snout, and brown-grey dorsal fur. Its ears are short and narrow ears and some individuals can exhibit a paler spot of hair between them. 

Unlike the M. myotis, this species favours warm and open habitats, such as damp meadows, pastures and other extensively farmed areas. Along the northern distribution area, attics are used as summer / maternity roosts, which can be shared with Rhinolophids and Miniopterus. During winter, the species may form clusters in underground sites.

The diet of M. blythii comprises of bushcrickets, crane-flies and grasshopers; these are caught primarily through gleaning techniques.

This species is considered an occasional migrant due to a few recorded distances of 100 - 150 km. More often than not, it has a sedentary behaviour and its summer an winter roosts are usually 15 km apart.

IUCN status: 
Least concem
Population Trend: 

Decreasing according to the IUCN Red List.
