This dichotomous key should enable the identification of all 16 British bat species.

The key is based on Jones and Walsh (2001), Stebbings (1986), von Helversen (1989), von Helversen & Holderied (2003) and information provided by G. Jones. The information is correct and accurate as far as is currently possible given the data available in 2005.
