I’m pulled to rivers that have hatches. I start the early season fishing midges, then olives, then the pale morning duns of summer, sometimes tricos, then back to olives in the fall and end the season as I began it, with midges. A full circle. Depending on the year, grasshopper imitations play a role mid to late summer and into the fall. I also sight fish from summer onward with other terrestrial patterns such as beetles and crickets when there is no hatch. Since I fish mainly small dry flies I try to keep my patterns simple and visible. If I can see my fly, I can fish well. Polypropylene wings are buoyant and flies tied in this material in white, black, or even orange show up well in varying light conditions. This material is also more durable than CDC, and I can resurrect it faster once slimed. This is important as a lot of the water I fish is rich, out of the main flow (flat) and has some surface scum. I also tie wings with fine deer hair generally cripple style (forward) and a lot of my small patterns incorporate a turn or two of hackle frequently clipped underneath so the fly rides low. When it comes to terrestrials I like foam as it always floats and is easy to tie with. Black is a great colour as it is noticeable to trout in bright or low light; it contrasts well. I use standard hooks but also like a Klinkhammer (emerger) bend. Of course when tying I pay attention to size, shape, colour and how the fly will sit in the water (attitude).
