Adults inhabit sand and gravel runs and pools of creeks and small to large rivers (Ref. 3814, 10294). They also occur in sandy margins of lakes. Usually found in clear creeks and small rivers and rarely in upland areas (Ref. 3814). Adults feed on detritus, and small benthic and drifting invertebrates dominated by midge larvae and small mayfly nymphs (Ref. 10294). Migratory behaviour is undetermined (Ref. 126106).
栖息于小溪与小型到大型河川的沙与碎石小支流与水潭。 也生活于湖的沙边缘中。 通常发现于清澈的小溪与小河而且极少在高地的区域。
