About: Salmon fly patterns

Salmon fly patterns (not to be confused with flies for Atlantic Salmon) are an important collection of artificial flies used by fly anglers to imitate nymphal and adult forms of Pteronarcys californica a giant stonefly or salmon fly. Salmon flies are common in high gradient, freestone rivers and streams from Western Canada throughout the Western U.S. to Mexico in the Rocky Mountains and coastal mountain ranges. Nymphs live for three to five years before adult emergence which typically occurs in late Spring or early summer. The long lifespan of the nymphal form provides year-round angling opportunities for fly anglers.
