Adults occur in cool pools of sluggish, clear creeks and small rivers, usually over sand or gravel; more abundant in cool acid waters of silt-bottomed bog ponds (Ref. 1998). They probably feed on phytoplankton and other algae, zooplankton, and aquatic insects (Ref. 1998). Oviparous, open substratum spawners (Ref. 205, 52559). Probably spawn in May or June over silty bottoms of calm waters (Ref. 1998). Predators may include brook trout, kingfishers, and mergansers (Ref. 1998). Migratory behaviour is undetermined (Ref. 126106).
