Mole Fly
Mole Fly is a sparse soft emerger pattern that excels when trout refuse high-floating dries and key on insects trapped in the film. It supports Mole Fly emerger, sparse CDC emerger, and technical film fly searches.

How to Rig It
Fish behind a small visible dry or alone on a long leader in calm water.
How to Present It
Grease only the leader and let the fly sit flush in the film with minimal drag.
Why It Works
Its sparse materials and low profile perfectly match the vulnerable stage trout often prefer.
History
Minimalist emerger patterns became essential on spring creeks and tailwaters where trout reject heavily dressed flies.
Pro Tip
If trout nose your dry but do not eat, tie this on as a trailer and watch your hookup rate improve.
