Comments: Adults occur on vegetation and debris in swamps, sloughs and quiet pools and backwaters of streams.  Found year-round in open streams which are small and well-shaded with temperatures never exceeding 23°C.  In such streams, thigmotaxic tendency is shown by the difficulty in seining these individuals from the roots and debris of their preferred habitat along edges of submerged weed banks which border sand-bottomed channels.  This habitat is rich in potential food for <i>C. cornuta</i> like amphipods, ostracods and copepods (Ref. 34868).  Eggs are carried in gill chambers of females (Ref. 205).
