Choosing Wet Flies 

Choose a wet fly around the food you want to represent and the presentation you plan to fish. Wet flies can be presented below the surface on a drift or swing, with current, depth and presentation affecting how the fly behaves in the water. 

Start with the fishing situation, then narrow the fly by profile, size and imitation rather than choosing a pattern name first. (Orvis Fly Fishing)
