Tying Recipe
  • Hook: Straight eye, straight shank, dry fly hook
  • Thread: 12/0 Veevus Black Thread
  • Body: Peacock herl
  • Hackle: Grizzly Whiting Rooster Dry Fly Cape
  • Body: Try dyed peacock herl to add a hue that most fly fisherman don’t have
  • Hackle: Use your favorite hackle to acquire the desired presentation for your favorite stream. White hackle can be a great option, especially if you bring colored markers to the stream- this allows you to better imitate whatever midges you see on the water.  (Note that hackle bred to be buoyant will work better for dry flies)

Being a fairly simple pattern, the Griffith’s Gnat can be frustrating if you try to change things up and make it your own. Don’t allow this to stop you because there are some really great tricks to try that will produce a serious amount of fish. Here are some ideas to get the creative juices flowing:

  • Articulation: The Griffith’s Gnat has a neat property in that it can imitate both a single midge or a midge cluster depending on the size and how you tie it. Adding a second “Griffith’s Gnat” can be a fantastic way to resemble a midge cluster that has just a little space in between mating clusters. If you choose to articulate this pattern, keep in mind that you will need to attach a fully tied Griffith’s Gnat to a bare hook using monofilament before you tie up the lead fly.
  • Segmentation: Spacing of your hackle fibers greatly changes how this fly floats and also can lead to a more desired level of precision. In general, fewer hackle wraps imitates a smaller number of midges, but is less buoyant. More hackle wraps lends itself to imitate more of a midge cluster and allows your fly to float better.
  • Thorax variation: Adding a few small wraps of ostrich herl at the head of this fly can be a good way to break free of the patterns other anglers generally use.
  • “Hot Butt”: Red Krystal Flash or red/pink thread at the back of this fly can be a good way to invoke a more predatory response, but may also elicit refusals in streams where fish are incredibly spooky (i.e. spring creeks).

The Griffith’s Gnats is one of the most productive flies that works essentially everywhere. All anglers should carry this pattern in their box. Whenever you are in a bind or see midges coming off in droves, the Griffith’s Gnat will produce fish. One of the better-floating midge imitations, the Griffith’s Gnat catches a lot of fish and is incredibly dependable. This pattern can be fished alone as a dry fly, or also as a second dry fly behind a bigger dry fly. When spotting soft-rising fish, casting a Griffith’s Gnat will provide the inquisitive angler with an ample amount of information as to its feeding patterns. A rise and take, or rise and refusal, will likely confirm if the fish are feeding on hatching midges. Use the Griffith’s Gnat as a key piece to unlocking the puzzle of fish feeding habits.

Starting your fishing trip with a Griffith’s Gnat on the tippet is never a bad call. Sometimes anglers spot rising fish, but readily receive refusals on the bigger mayfly and caddis dries. Other times, the midges are coming off in masses and this is the go-to fly. Whatever your situation, be sure to use the Griffith’s Gnat to obtain information on the feeding habits of fish in your observed hole. A rise and take, or rise and refusal, will likely confirm if the fish are feeding on hatching midges; this is true whether other insects are hatching or not. The important piece to consider is what to do following a rise and refusal. Watch the body language of the fish very closely; does he rise to within 6 inches of your fly? Is the take mainly a dorsal rise? Does she open her mouth and begin to sip your dry? Pay close attention to the actions of rising fish; generally if the fish rises to within 6 inches of your fly or begins to take, the fish is feeding on midges and you will produce with the Griffith’s Gnat. In this case, tying on a smaller fly, or smaller tippet, is the way to go.
