My post of 01/01/2012 provides a nice background story to how I became acquainted with the emerald caddis pupa, and it also provides a materials table. I continue to admire this fly and its fish attracting capability. Unlike the bright green caddis pupa or go2 sparkle pupa, the emerald version seems to entice fish throughout the season, not just during the heavy grannom period. For this reason I give it more opportunities on the end of my line. During the early season before snow melt and then again in the fall, I elect to pair the emerald pupa with a beadhead hares ear nymph, and it often results in a sagging net.
I am convinced that the emerald green color is an outstanding fish attractor. I have seen caddis larva with body colors that approximate the emerald green, so that might explain some of its effectiveness. I also caught several recently hatched adults and noticed the emerald green color on the tip of the abdomen on otherwise charcoal gray bodies. My logic dictates that trout are conditioned to seeing this color on tasty morsels, and they are readily drawn to my pupa imitation.
I counted twenty-eight in my various storage containers, so I situated myself at my tying station and cranked out seven more to bring my total to thirty-five. This quantity is in line with my starting inventory for previous seasons, and I look forward to swinging and drifting the emerald caddis pupa again in 2018.
