Griffiths Gnat

Hook: Tiemco 100 or 101 - standard dry fly hook

Size: 16-22

Thread: 8/0 black

Body: Peacock herl

Hackle: Grizzly

 

Notes: George Griffith originated this fly for midge clusters. I have found it to work even better for Trico hatches on tailwaters like the Missouri River in Montana.
