I finally got off my ass (see 3.23.15 post), sat down on it, and tied in front of the camera with Tim Flagler this past Sunday. This fly is a simple but effective midge emerger pattern originated by Rene Harrop for his ultra tough home water, the Henry's Fork of the Snake River in Idaho. Like most Harrop patterns, the second you look at this fly, you know it is going to work. It may be small, but it is fairly easy to tie - three materials - and you can change the body color to match any midge on your home water.
Hook: TMC 100 #20-24
Thread: 6/0 Olive Danville (what else?)
Tail/Shuck: Grizzly hackle tip
Overbody/Legs/Head: Natural CDC puff
Body: Australian opossum - natural
What could be easier? With a little practice you can knock these things out in no time and be prepared for those snotty little smutting trout that are feeding on midges and won't take standard fare. If you have trouble seeing them on the water, tie on a larger dry first, then tie about 20 inches of tippet to the bend of that fly to which you then tie this fine pattern. No reason to make things more complicated than they have to be.
Sharpen your hooks!
