The serotine bat (Eptesicus serotinus) is a fairly large Eurasian bat with quite 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.


Similarly to Nyctalus or Plecotus species, the Serotine is mainly an aerial hawker focusing on hunting flying prey.[2][3][4]


The frequencies used by this bat species for echolocation lie between 25–55 kHz, have most energy at 31 kHz and have an average duration of 8.8 ms.[5][6]
