Thats a great fly to start a noobie fly tier on.
I tie a very similar fly but with a white bead. I think it gives trout the idea of the red worm stage of the chronomyds and the white gills of the chronomyd emerger sort of a double whammy.
Anyway it works amazingly well in small lakes for trout. I use a sinking line on small lakes, let it fall almost to the bottom. ( you have to time its fall toward the bottom ) then slowly bring it up about a foot or so in a slightly jerky motion letting it fall back down for about 6 inches or so then up another foot or so then another fall repeat this motion till it is finally near the surface. It simulates the upward travel of a cronnie in the water column. You often get a violent take as it finally nears the surface of the water.
Nice tie by the way.
