Abstract With the purpose to know the diurnal and nocturnal activity of O. tuberculata on the surface of a sandy beach of Southern Chile (Mehuín, Valdivia Province), 26 hours samples were made in the 1974 spring and 1975 summer and winter. Activity was measured by traps placed on transections between the cliff that limits posteriorly the beach and the low tide level. Each two hours the captured animals were taken and counted. Adults showed activity preferably in night hours, sub‐adults in sunset ...
