I am often asked, at times, what is your all-time favorite surface fly to fish on the Sipsey Tailrace and Simth Lake during the Spring and Summer months? My response is the Caddis dry fly. For this post, I will only cover the surface aspects of this fly, not the subsurface stages the fly goes through to become airborne. Why is the fly so effective in fly fishing? It's a staple in the diet of many fish species, particularly trout, and it's so realistic that it can trigger fish to strike it even when other flies don't produce. Caddis flies are widespread in streams and rivers across many regions, making them a familiar and reliable food source for fish. When a hatch occurs, fish actively hunt them, making caddis fly patterns incredibly productive. They have a unique, skittering movement across the water surface when they emerge to the surface film. Skittering can produce an automatic bluegill, bass, or trout strike that might otherwise be a static fly.
The presentation of the caddis plays an integral part in the angler getting the fish's attention. I strive to get the fly to light on the water's surface as if it fell off an overhanging limb on the bank or if it has just touched the water's surface lightly. Most of the time, no movement of the fly is needed to get attention from bluegill, bass, or trout, but a slight movement of your tippet will guarantee a hit if the fish is near.
As most of you know, dry flies need help staying afloat, whether in choppy water or on calm days. Over the past couple of years, I have experimented with different types of floatants, and this year, the product that really got my attention was the Fly Shack brand "Stay Dry." I used it this year and found that I could fish the fly for several hours before reapplying the solution; it’s an excellent product!
When other flies fail to attract fish, it often indicates that the fish are either uninterested in what is being offered or are spooked by unnatural presentations. Due to its realistic movement and variety of color patterns, the caddis fly is one that I will continue to use for the rest of my fishing days.
