Mercer's Poxyback Isonychia

Mercer's Poxyback Isonychia

Isonychia are large mayflies, often called Slate Drakes. Their hatches can be exceptional and long lasting and the nymphs are very strong swimmers. As larger mayflies, trout key in on them very quickly under the old calories gained for calories burned equation. This fly is an excellent pattern to swim in riffle water where Slate Drake flies (Isonychias) are known to hatch. Color, Natural. Fly available in sizes: 10, 12.

"Incredible on mid-summer Vermont trout and smallmouth. Swim it just under the surface of deep pools and still ponds in the late afternoon and you'd better have a tight grip on your rod!"
