Several years ago I was fishing on the Eagle River with my friend Todd, when he showed me a fly that generated a couple landed fish. It looked like a mutated caddis fly with a spent wing and a vertical wing. Todd informed me that the fly was called a missing link. I filed this information away, as a fly to investigate, but I never acted on my intention.
A recent issue of Fly Fisherman Magazine featured an article by Mike Mercer of The Fly Shop in Redding, CA; and in the article Mike described how he created the missing link, and how it evolved from a spent wing caddis imitation to a potent all around attractor. Mike proclaimed that the missing link produced in a variety of hatch situations including both mayfly and caddis emergences.
I completed my standard production tying of known producers for the upcoming season, and the combination of the two factors above prodded me to find tying instructions for the missing link. Fortunately a YouTube search yielded a video starring Mike Mercer himself, and I followed the steps as presented by the originator of the missing link pattern.
I created five size 16 missing links, and I was quite pleased with the outcome. These flies look exceptionally buggy, and I understand how the narrow flashy abdomen, spent poly wing, tilted elk hair wing, and parachute hackle create a very versatile dry fly. I personally found the fly a bit difficult to tie as a result of wrapping the parachute hackle around the elk hair wing and the small butt end stubble. Tying off the hackle feather and then finishing the whip finish were a challenge with the amount of material coming together near the eye of the hook. Despite this challenge, I feel that my flies are solid copies of Mercer’s creation, and I am anxious to float them on western streams in the upcoming season.
