## Summary

The serotine bat (Cnephaeus serotinus) (Formerly Eptesicus serotinus), also known as the common serotine bat, eurasian serotine, big brown bat, or silky bat, is a considerably large Eurasian bat with large ears. It has a wingspan of around 37 cm (15 in) and often hunts in woodland.  It sometimes roosts in buildings, hanging upside down, in small groups or individually. The name serotine is derived from the Latin serotinus, which means 'evening', while the former generic name derives from Greek ἔπιεν and οίκος, which means 'house flyer'.
