Designed by George Griffith, the Griffith's Gnat is an easy fly to tie and is one of the best patterns to imitate a cluster of midges. Midges are a ubiquitous insect, and a hatch can occur almost any month of the year, which is why this is a pattern that you should always have on hand.

Materials

Step One

Begin the pattern by running the thread from the hook's eye to the bend, then clip the excess thread.

Step Two

For the second step, take a strand of peacock hurl and pop the tip-off it. Pinch wrap the hurl at the eye, pull the material slightly to the left, then wind the thread to the bend.

Step Three

Secure a piece of grizzly hackle at the shank's curve, with the majority of the material facing rearward. Advance the thread forward, then clip the excess feather.

Step Four

Now that the Griffith's Gnat's materials are tied in, make evenly spaced wraps with the peacock hurl. To create a smooth underbelly, be sure to overlap each wrap tightly. Once the hurl is advanced to slightly below the eye, pull the material rearward, secure it with a half-hitch, and clip the extra fabric.

Step Five

Going back to the grizzly hackle, snap the neck and palmer the material forward.  Tie the hackle in once you have reached just behind the eye, then clip the excess fibers off.

Step Six

For the final step, pull the material back and secure the pattern with a whip finish. Now it is time to fish a midge hatch!
