The serotine bat (Eptesicus serotinus) is a fairly large European 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.

Diet[edit]

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

Echolocation[edit]

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]
