#20 Fore & Aft Midge
The Griffiths Gnat is a pattern that has been around for a very long time. For the most part this pattern mimics a midge cluster using hackle spun around a full shank of peacock herl. It quite honestly looks like a tiny round ball of dust. It has been a popular staple fly for many many decades. The main problem I have with the Griffiths Gnat is that it represents a very specific profile that imitates multiple insects latched together. It does not necessarily represent the single midge in its shedding pupal stage, which in my opinion, is one of the most important life stages of the insect. Selective trout will often be zeroing in on individual insects shucking in the surface film.
The Fore and Aft Midge represents the insect in an impressionistic manner giving it the profile of the pupal stage breaking out with legs (fore) emerging and a trailing shuck (aft) trailing behind. This pattern is very easy to tie and has been my go to fly for decades. This fly is extremely durable and floats like a princess even after multiple strikes and hook ups making it more valuable in my fly box than my CDC midges. I have written at least a half dozen articles on this pattern over the years but tying these little guys never gets tiring. The Fore and Aft Midge can be tied in black, olive, dun, and tan depending on conditions and season. The rear hackle I typically use light dun, bodies comprised of quills, stripped rooster hackle and dyed. Peacock quills are also very effective on this pattern for bodies. For the trailing shuck I use duck flank either lemon or natural or alternatively you can use Tiemco Aero Dry Wing in light dun and singe the fibers at the tips with a lighter. My preferred hook is TMC 531 in sizes 18-22.

A very tiny simple fly but probably the deadliest in my midge arsenal.
