Product Description

Mimicking one of the most vulnerable life cycles of the invertebrate, the foam wing of the Mayhem allows it to dance and bob in the water column in a spot-on imitation of a small invertebrate trying to emerge.  Equally deadly when fished off the bottom of the river or close to the surface, the Mayhem bridges the gap between mayfly and midge, and is a 4 season match for a host of invertebrate species.

Dry/Wet:  Wet

Fly Category: Generalist Pattern

Family: Mayfly, Midges & Chironomids

Species: Blue Winged Olive, Trico, Black Fly, Chironomid, Mosquito

    Nicely tied fly. I haven't had it in the water yet but I expect great things.
