Natural history.
In NB, most specimens of Dianous nitidulus were found along fast-flowing, cold, shaded brooks, shaded streams, and shaded river margins. Adults occurred on rocks or in moss (often saturated with water) on rocks on the stream margin and within the streams themselves. Some individuals were found on gravel bars or on clay/sand along shaded brooks and river margins. Adults were collected by splashing moss, rocks, and gravel in the above habitats, in May, June, July, and September.
