Collection and habitat data.

Negastrius atrosus adults were collected along river margins from under small rocks, in gravel, and under drift material on sand bars. Two adults were collected by splashing water onto sand on a sand bar. Adults were collected during May and June. No details on the habitat requirements of this species were given in Wells (1996). Wells (1996) reported that other species of Negastrius were associated with riparian habitats and inhabit sandy–to–rocky stream and river margins.
