Stoneflies (Plecoptera): A Comprehensive Overview Stoneflies , belonging to the order , are a primitive group of aquatic insects that serve as critical indicators of ecosystem health. With over 4,000 described species globally, they are primarily known for their high sensitivity to pollution and their essential role in aquatic food webs. Biological Classification and Diversity
: Recent genomic studies, such as those on Nemurella pictetii and Protonemura montana , have successfully assembled chromosomal-level genomes, providing insights into their evolution and sex determination. Life Cycle and Metamorphosis
: There are approximately 3,500 to 4,000 species found on every continent except Antarctica.
