A faunal survey of bats in Osorezan district, Aomori Prefecture in 1979-1982, revealed inhabitation of the following eight species belonging to five genera; <I>Rhinolophus cornutus cornutus, Rhinolophus ferrumequinum nippon, Myotis hosonoi, Myotis frater kaguyae, Myotis macrodactylus, Vespertilio superans, Pipistrellus endoi</I>and<I>Murina silvatica</I>. Among them, <I>P. endoi</I>constitutes a new record in Aomori Prefecture.<I>My. hosonoi</I>and<I>Mu. silvatica</I>were the most common species in this district. Dominant species differed with different study areas. Most of the specimens of<I>P. endoi</I>and<I>My. macrodactylus</I>were caught over rivers. In forests, the f aunal composition and the number of bats were poor. The activity of bats in summer showed one large peak between the times of 19: 00 and 21: 00 and two small peaks between 22: 00 and 23: 00 and between 4: 00 and 5: 00. It seems that the following six species were lactating in mid-August ; <I>R. c. cornutus, My. hosonoi, My. f. kaguyae, My. macrodactylus, P, endoi</I>and<I>Mu. silvatica</I>. Newly weaned young of the following four species had foraging flights in mid-August; <I>My. hosonoi, My. macrodactylus, P. endoi</I> and <I>Mu. silvatica.</I>
