Nymph
Hexagenia Nymph
Giant silt-bed burrower
TroutSubsurface
Huge burrowing-mayfly nymph of silt-bottomed lakes and rivers — fished deep before the night-time Hex emergence.
Fish this when
On warm summer evenings over silt-bottomed lakes and slow rivers, fished deep near silt beds in the hour before the after-dark Hex emergence.
Why it works
Hex nymphs migrate out of their burrows en masse ahead of the famous night hatch, and in low light it's the sheer size of this fly, not fine detail, that fish are keying on.
