I find that a lot of people have a hard time distinguishing the aquatic insect nymphs with tails sticking off the back, the mayflies, the damselflies, and the stoneflies. The nymphs of many species are 'opportunistic feeders', meaning that they feed on what is around, while others may select for specific prey species or sizes. Stonefly is an aquatic insect from the order Plecoptera. The ecological requirements of nymphs and the reduced flight capacity of adults are the main factors responsible for their high endemicity (Fochetti and Tierno de Figueroa, 2008).
