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.
Many anglers believe the name Stimulator was given to the pattern by Jim Slattery, a Montana angler who renamed his Fluttering Stonefly pattern. 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 ...
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. Although the Pteronarcyidae are primarily shredders-detritivores, some facultative scrapers occur.
Zelandoperla fenestrata is a widespread endemic New Zealand ‘long-tailed’ stonefly that is often abundant in high-gradient stony streams, from near sea-level up to alpine elevations. [1] The species name 'fenestrata' refers to the window-like rectangular patterning visible on the wings of non-melanic adult specimens.

Nymph of a golden stonefly, Plecoptera, Perlidae Dinotoperla imago (adult) (Gripopterygidae: Dinotoperlinae) Stoneflies have a generalized anatomy, with few specialized features compared to other insects. They have simple mouthparts with chewing mandibles, long, multiple-segmented antennae, large compound eyes, and two or three ocelli. The legs ...
Amphinemura nymph.. The Nemouridae are a family of stoneflies containing more than 700 described species, occurring primarily in the Holarctic region. [1] [2] Members of this family are commonly known as spring stoneflies or brown stoneflies.
For instance, the New Zealand black stonefly Austroperla is a forest dwelling shredder that is toxic to predators due to its production of hydrogen cyanide. [4] The warning colouration of this species is mimicked by several lineages of the unrelated non-toxic New Zealand stonefly Zelandoperla .
