The European free-tailed bat. (Tadarida teniotis, sometimes given as Tadarida insignis) is a species of free-tailed bat found in the Old World. Other common names include the bulldog bat and the mastiff bat because of the presence of wrinkling on the snout. This bat is found in the Mediterranean region of Europe and in scattered locations across Asia at altitudes from sea level to 3100 m. It was reported from Korea in 1931, but has not been sighted on the Korean Peninsula since that time. Populations in Japan, Taiwan and Korea are now considered to be a separate species Tadarida insignis.
