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.
The colouring can vary, and subtle patterns are occasionally found on the abdomen. They are detritivores , eating stream debris partially broken down by other organisms. They are "shredders" as a functional feeding group, breaking down large bits of detritus down into smaller ones while feeding. [ 2 ]
They live in a lotic-erosional habitat. Larvae of giant stoneflies live in cool streams of small to medium size, in leaf and woody debris packs. They prefer swift riffles between cobbles and boulders.

Others contend the pattern was derived from the Trude style dry flies developed in 1903. However, the pattern was clearly popularized and promoted by Randall Kaufmann, a fly shop owner, angler and ...
