Emergent Sparkle Pupa
When caddisflies are ready to hatch, they leave their pupal cocoon and get ready for their ascent to the surface of the water. Most species exude gases from their newly formed adult body. This gas is trapped by the old pupal skin which still surrounds them. This process starts to separate the adult insect from the pupal shuck. The shuck is inflated, forming a bubble or balloon around parts of the adult insect and the gases within this bubble reflect light. Each caddis pupa becomes a reflective, buoyant orb as it swims and rises to the surface. Gary LaFontaine has spent quite a bit of time viewing caddis flies in various stages of their life cycles and wrote his doctoral thesis on the subject. He has noted, in his revolutionary book Caddisflies, that these reflective qualities make the caddis pupae highly visible to trout. The bubble becomes a key target for feeding fish.
In today?s modern world, there are many new tying materials that have led to innovative fly patterns. Although these patterns are quite detailed and realistic, many do not act as naturally as they could in the water. A lot of fly designers tie what they think the fish see, but have never actually seen what goes on below the surface from a fish?s eye view. This is where Gary LaFontaine's Emergent Sparkle Pupa has the edge. They are tied with a bubble of Antron fibers around the body to trap air and reflect light much the same as the real insect. This fly not only perfectly mimics an emerging hydro cyclic caddis, it revolutionized fly fishing during a number of important caddis hatches and is a tried and true pattern that has stood the test of time. We here at The Fly Fishing Shop are firm believers in this pattern. The Deschutes has caddis fly activity year round, so every local fly angler should be prepared with a few of these in his or her box. It is truly one of the most important patterns to have in your box when fishing Western streams.
