Rocky and sandy pools of creeks and small to medium rivers; rocky and vegetated lake margins (Ref. 5723). Adults feed on terrestrial insects and both immature and adult aquatic insects, particularly larger varieties such as mayflies and dragonflies. Juveniles consume benthic organisms such as dipteran larvae (Ref. 10294).
小溪及小型到中型河川的岩石而沙水池; 岩石與長滿植物的湖邊緣.(參考文獻 5723) 成魚吃陸棲的昆蟲與不成熟的與成魚水生昆蟲, 特別比較大的變種例如孚游類與蜻蜓。 稚魚消費底棲的生物例如雙翅類昆蟲的幼生。 (參考文獻 10294)
