After discovering Leisenring, I realized that his "Black Gnat" much more closely resembled a real gnat, and I have caught many trout with this pattern. I never leave home to go fishing without having a few handy. I once tied up a few for a student of mine. He actually fished them off a bridge using a light spinning outfit and a casting bubble. He took his limit-which was ten trout at that time-using the out fit and the Black Gnat tied on a size 14 Mustad 3906.
Since then, I have added a very fine green wire rib for strength. To me it mimics an iridescent gnat body.

I really like Williams as well!
