I caught a Chironomid yesterday and tied this up after watching these gnats getting taken out by rain and the trout taking the crippled surface film. It was fun to watch the gnats buzz around dippin' thier butts in the water and in one spot under a log was a trout that would surface but I could not get him out with a dry. Well should do the trick. Spalsh down and let sit and sink. . .like a spinner but for freshwater. The pic shows the bug I caught and one of patterns model after.
