March Brown Nymph
Spring stone-clinger nymph
Trout · GraylingSubsurface
Flat stone-clinger nymph of fast spring water — the March Brown nymph dead-drifted deep.
Fish this when
In early spring on fast, stony UK rivers ahead of the March Brown hatch, dead-drifted deep and tight to the streambed.
Why it works
Clinger nymphs like Rhithrogena hug boulders and only enter the drift briefly before hatching, so fishing deep and close to structure catches them at the one moment they're genuinely exposed.
