Plecoptera is an order of insects commonly known as stoneflies, with some 3,500 described species found worldwide except Antarctica. Stoneflies are considered among the most primitive living groups of Neoptera, with close relatives known from Carboniferous and Lower Permian fossils, though most of their present day diversity appears to have arisen later, in the Mesozoic.
