Plains clubtail nymphs can be very selective in their habitat choice and will often occur only in certain stretches of a particular river or stream. They will burrow into the sand or mud, leaving the upturned tip of their abdomen exposed. This helps them to breathe while buried by pumping water in and out of the tip of the abdomen.
