The grey long-eared bat (Plecotus austriacus) is a fairly large European bat. It has distinctive ears, long and with a distinctive fold. It hunts above woodland, often by day, and mostly for moths. It is extremely similar to the more common brown long-eared bat, and was only distinguished in the 1960s, but has a paler belly.

While Continental European distributions are not threatened, a 2013 study found this species was close to extinction in the United Kingdom.[1]


The frequencies used by this bat species for echolocation lie between 18–45 kHz, have most energy at 28 kHz and have an average duration of 5.8 ms.[2]
