Description
Griffith’s Gnat
Griffith’s Gnat is a popular fly pattern used by fly fishermen around the world.
It was created by Craig Mathews, a fly fishing guide and owner of Blue Ribbon Flies in West Yellowstone, Montana, in honor of his friend George Griffith, who loved to fish the Madison River in Montana.
The fly pattern imitates a small midge or mosquito, and is typically tied on a size 18-22 hook.
The body of the fly is made from a small amount of black dubbing, and the wings are made from a few strands of white or cream-colored hackle tips. A tiny tuft of white poly yarn is often added at the head of the fly to help the angler see it on the water.
Griffith’s Gnat is a versatile pattern that can be fished in a variety of ways. It is often fished on the surface as a dry fly, either on its own or as part of a dry-dropper rig.
It can also be fished below the surface as a nymph or emerger, and is particularly effective when trout are feeding on small insects such as midges or small mayflies.
Overall, Griffith’s Gnat is a simple yet effective fly pattern that every fly fisherman should have in their fly box.
