'' Pteronarcys californica '' (Newport), the giant stonefly commonly called the salmonfly, is an aquatic species of the family Pteronarcyidae. == Characteristics == ''P. californica'' nymphs, or larvae, can grow to lengths in excess of . The nymphs' dorsal side (back) is dark in color, although their ventral side (belly) is lighter. The coloring can vary, and subtle patterns are occasionally found on the abdomen. They are allochthonous (detritus) feeders, eating stream debris partially broken down by other organisms. Their feeding technique has earned them the name of "shredders". The adults are also large, and the abdomen, leg joints, and several thorax joints are a bright orange color (see photos). Two pairs of large wings, kept flat against the body when at rest, are nearly as long as the body.
