» Family Pteronarcyidae (Salmonflies)
Common Name
This family contains the largest species of stoneflies in North America, with many female specimens exceeding 50mm. Unlike the large and active predaceous Perlidae Golden Stones, they are primarily detritivores (Detritivore: eater of plant and animal debris) that move about slowly. The most important species is Pteronarcys californica. See its hatch page for details. It takes them three years to develop to maturity, so it is useful for the angler to carry a variety of nymph sizes.

High Water 8 Replies »The hatch often occurs during high water (just after peak) so you sometimes have limited visibility during the hatch. Also - I believe that they can occur above 7000 feet.

ChipperI don't have many reliable sources about this species, so it'd be great if you western fishermen could read over the article and make sure I haven't said anything stupid or omitted anything important. I'll be happy to incorporate any additions you have.

TaxonAre stoneflies and salmonflies the same thing or are they just related because here in the mid west we have the stonfly hatch and if they are related the stonfly could be called the salmonfly and the salmonfly hatch is only in the west because I have trouble because I want to become a better insect identifier when it comes to fishing because i went to other sites that so a stonefly is a stonefly and a salmonfly is a salmon fly but yet you say stonefly nymph but in parenteseses you have american salmonfly so is there really no such thing as a salmonfly but it is rather called a stonefly.
