I spent quite a bit of time searching for a Black Stone Fly pattern that was not too difficult and was representative of what we have here on the the Salmon River in NY. I found the following post, and tried to imitate it as close as possible.
Black and Brown HW Stone Fly
Easier said than done. First, I've been tying only about a month. Second, I found it very difficult to get the biots to tie in correctly for the legs. In the end I tried a number of different options. Here are pictures of what I tied. I'm not sure ANY of them look like a stone fly. I know proportions are off, antenna are not the same length, etc. I'm just looking for some suggestions on which one(s) look the closest so I know which one to pursue. Any and all suggestions are appreciated.
