Plecoptera, NYMPH
Trout · GraylingDeep
Chenille body, rubber legs at every joint — a big, buggy stonefly nymph that has anchored a thousand Western and Alpine rigs. Crude up close, irresistible on the drift.
Fish this when
The point fly on a heavy nymph rig in fast, broken or coloured water, especially early season and after rain when big stonefly nymphs are dislodged.
Why it works
The rubber legs never stop moving in the current, and the sheer size offers a calorie-rich target a trout will move for even when it is not actively feeding.
