Species details: 

Geoffroy's bat has a wingspan of 220 - 250 mm and a distinct notch on its brown ears. Its wooly and dense dorsal fur is tricoloured (grey, rust brown and red), while yellow and grey are present in its venter.

This species can be found in hardwood forests and is considered a cave-dwelling species, despite often roosting in buildings. M. emarginatus males tend to hibernate alone and females form maternity colonies that in average include 200 individuals.

While foraging, Geoffroy's bats tend to avoid open spaces. Instead, they prefer to hunt spiders, moths, lacewings and Diptera through foliage gleaning techniques.

M. emarginatus is regarded as relatively sedentary as its winter and summer roosts are usually less than 40 km apart. However, longer distances (e.g. 105 km) have been recorded.

IUCN status: 
Least concem
Population Trend: 

Stable according to the IUCN Red List.

Distribution map of Myotis emarginatus
Geographic Range: 

M. emarginatus can be found throughout the entire Mediterranean area and further east towards Asia Minor. However, a rather large gap in the distribution occurs between Luxembourg and Poland.


In Europe, habitat fragmentation and intensive agriculture can be problematic. In addition to cave disturbance, the collection of the species for traditional medicine practices in North Africa can be considered a threat.
