Griffith's Gnat
Griffith's Gnat cracks the tiny-bug code - a pinch of peacock and grizzly that reads as a cluster of midges, fishable at sizes your eyes can almost see.
When trout sip something invisible on winter flats or evening scum lines, they're usually eating midges - insects so small that imitating ONE is misery. George Griffith's gnat imitates several at once: a scraggly peacock-and-grizzly pill that trout read as a mating cluster, letting you fish size 18 where the naturals run 24.
What it imitates
A cluster of adult midges - the little black flies of every cold month - riding tangled together in the film.
When & where it wins
Winter and shoulder-season risers, tailwaters, lake scum lines, any 'they're rising to NOTHING' puzzle - the answer is usually midges, and this is the answer to midges.
How to fish it
Dead-drift on long fine tippet (5-6X) to sipping fish; grease the leader, watch the dimple where your fly should be, lift gently at any rise there.
Sizes & variants
18-24 (18-20 fish surprisingly well even when naturals are smaller - it's a CLUSTER); a hi-vis post version saves eyes.
Tying notes
Two materials, one fly: peacock herl body, palmered grizzly. The easiest tie in the book at the hardest size to hold.
Common mistakes
Fishing it on thick tippet that torpedoes the drift, striking too hard on 6X (lift, don't yank), and not fishing midges at all because 'too small' - they're the year's most reliable hatch.
