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).
