If I had to pick one small dry fly an angler could use to build confidence in fishing small flies it would be a Griffith's Gnat. Just like a Stimulator does a great job of imitating many larger insects the Griffith's Gnat is a great fly to imitate the smaller one's. With that being said if I had to pick one small fly that was nearly impossible to see on the water it would also be a Griffith's Gnat. Despite it's usually diminutive size which doesn't help matters, a standard Griffith's Gnat sits so low in the surface film it practically disappears. This is both a blessing and a curse to the angler as it's low stance in the water is one reason I think it's so effective. It was with this problem in mind that I sat at my vise one night after a day of fishing, or rather trying to fish, standard palmered hackle Griffith's Gnats to a pod of "Smutting" Trout.
I usually end a days fishing at the vise tying more of a pattern that worked or tweaking one that did not and that night it was the Griffith's Gnat that needed some tweaking. After a few failed attempts I settled on the pattern below. By turning the fly into a parachute pattern I had a Griffith's Gnat that would still sit low in the surface film like the original but remain highly visible even in the smallest of sizes. I also replaced the peacock herl body of the original with more durable and flashy synthetic peacock dubbing that adds added life and attraction.
Unfortunately I didn't invent the Parachute Griffith's Gnat but that night at the vise you would have thought I did! I personally love small flies but yet another reason that others do not is they hate tying them! Not only is a Griffith's Gnat a good entree into fishing small flies but also a good entree to tying them. After all, the only difference between a big fly and a small fly is their size. As far as I'm concerned if you can tie 'em big you can tie 'em small and with a Parachute Griffith's Gnat you can fish 'em small too!
