Check out my 01/11/2017 post for the story behind the creation of this productive fly. It continued to excel during the early season of 2017, particularly during the prime grannom emergence period. I deployed the bright green emergent caddis pupa with a dubbed body as well during the previous season, but I now view the go2 sparkle pupa version as my prime choice.
I like to jig and swing this fly in April and early May to imitate the active grannom pupa on western streams. Quite often the fish are tuned into the image of an emerging or escaping pupa, and a lift or bad mend initiates a grab.
A count of my go2 sparkle pupa flies revealed a supply of twenty-five. I visited my vise and created five additional facsimiles to boost my total to thirty for the new season.
