Plecoptera are an order of insects, commonly known as stoneflies. There are some 1,700 species worldwide.

These are aquatic insects whose nymphs (immatures) live in streams (running waters) while the adults live in the air. The name means pleikein, braided, and ptera, wings. They are called stoneflies and posess two pairs of wings which are membranous and fold flat over the back. Both nymphs and adults have long paired cerci, or tails, projecting from the tip of their abdomens.

A wingless species called Capnia lacustra is unique since it is the only known insect that is fully aquatic from birth to death.
