This Plecoptera Society of North America (PLSA) website is dedicated to the insect order
Plecoptera, or stoneflies. Plecoptera comes from the Latin plecto,
meaning folded and the Greek pteron, meaning wing, and refers to the ability of adult
stoneflies to fold their wings. Stoneflies worldwide are comprised of 16 families,
have a little over 2,000 described species, and reside on every continent except Antarctica.
They are among the most sensitive of aquatic insects, with many species in danger of extinction
and severe range reduction.
Our mission is to provide stonefly researchers, aquatic biologists,
undergraduate and graduate students, and the general public with information and
research tools for North American stoneflies.
A committee has been formed to establish a stable web presence and decide
which resources and tools are desirable.
Changes will occur frequently over the next couple of years, so keep looking.
