in the family Rhinolophidae. It is found in the Mediterranean region and Balkan peninsula, as well as parts of Italy.

Physical characteristics

The head and body are normally between , with a tail. The wingspan of R. euryale is between , with a standard weight between . The upper connecting process is pointed and slightly bent downwards, and is distinctly longer than the lower connecting process, which is broadly rounded when seen from below. The fur is fluffy, with a light grey base. The dorsal side is grey-brown, with sometimes a slight reddish tinge, while the ventral side is grey-white or yellow-white.

Biology and behaviour

There is little known information about the Mediterranean horseshoe bat's reproductive cycle. Nurseries normally hold between 50 and 400 females, with males sometimes present. The colonies in the summer and winter are very large and they are surrounded by small satellite colonies. The main colonies are in caves and can include over 5,000 animals, the satellite colonies include dozens to hundreds of animals. In the summer, colonies are mixed with other species. In Bulgaria the Mediterranean Horseshoe bat is living with the Blasius's horseshoe bat and the Mehely's horseshoe bat. The species is very sensitive to disturbance. The birth occurs from mid-June or July. At the age of four weeks, the young become independent. Females give their first birth at the age of 2–3 years. Mating takes place in the Autumn in caves, but may continue in the winter roosts.
