It hunts above water, for mosquitoes, caddy-flies and may-flies. Important indicator species due to its sensitivity to habitat and nutritionbase. It is well traceable in large numbers in all sampling areas, though in the Lankóci forest it is rarer, because of lack of open water surface. Pond bat {Myotis dasycneme) Endangered, rare species. So far it has only been indicated with detectors. Its life-style is similar to the Daubenton's bat's {Myotis daubentoni), but it is more connected to the old willow forests. It is endangered in its whole habitat (SCHOBER & GRIMMBERGER. 1987). In Ortilos and in Vízvár some individuals are regularly detected, in Babócsa at the backwater of Drava several hundreds of individuals were detected in 2001, but since then it has only been seen occasionally. Bechstein's bat {Myotis bechsteini) Endangered, rare species. Nowadays it is vulnarable all around Europe, in our country it was only known from the mid-mountains. Hence its presence in the plains is fairly remarkable! It is closely related to old, mixed, hardwood forests. Its nutrition consists of moths and mosquitoes. Except for Ortilos it was caught everywhere and its reproduction
