Inhabits small rivers that are tannin stained, acidic, very soft and deficient of dissolved substances, with compacted clay/sand bottoms, overlain with organic detritus. Also found in large rivers with a markedly seasonal hydrological regime, substantial flood plains and water ranges from clear to turbid water, but are not tannin-stained, are less acidic, harder and carry a greater concentrations of dissolved minerals (Ref. 57724). Feeds on terrestrial and aquatic insects and preyed upon mostly by fish-eating birds and dragonfly nymphs (Ref. 57724).
棲息於小的河那是單寧酸沾染, 酸性的﹐非常軟的與不足的溶解物質, 具有緊密的泥土/ 砂質底部, 覆蓋著有機的碎屑。 也發現於大河具有一個顯著季節性的水文制度,重要部份氾濫平原與水範圍從清澈至混濁的水, 但是不是單寧酸-沾染, 是比較不酸性, 比較堅硬的而且運送溶解的礦物較大的集中.(參考文獻 57724) 吃陸生與水生昆蟲而且大部份被吃魚鳥與蜻蜓蛹捕食.(參考文獻 57724)
