This topic is about the Stonefly Species Pteronarcys dorsata

This is the largest common eastern stonefly. It's quite abundant in places, but not to the extent of its western counterparts, and since most of its activity is at night it is generally less important. Nevertheless, nymph imitations produce some very large trout, and lucky or very locally knowledgable anglers may find good fishing to the egg-laying adults. Read more...

Posts: 1Are 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.

I think the answer to your question, Max, may be found at the top of this thread - I would trust this site above all other fishing sites when it comes to insect IDs. Jason has made a nice section called "Common Names" (the link is in the menu at the top of the page) in which you can find the sometimes varied species associated with the myriad common names fishermen apply to these bugs. Click around that section for a few minutes and you'll see how nicely Jason has designed it. He's made a very complicated body of information at least easy to navigate.


P.S. One of the things that makes this site so reliable is the number of experts in insect ID who frequent it and offer their expertise to the rest of us for free. Someone knowledgeable to answer your question in 3-2-1...

Salmonfly is the common name for family Pteronarcyidae, which is but one of the stonefly families. Perhaps, this can be seen more easily here.

Wow- I knew Roger would respond but I didn't think it would be that fast.
When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

I took 2 pictures of a handfull of my salmonflies, a couple i tied(poorly) and a couple i bought. The are on a size 4-10 hook, although i currently dont have any of the larger ones, the salmonfly hatch is still about 4-5 months away.
