While caddis hatches on the Yellowstone River were sort of “meh” in 2019, the nymph fishing during caddis season was quite good. Usually we fished our nymphs as droppers, sometimes deep under bobbers. Either way, my most-productive caddis/attractor nymph was an old tie by Matt Minch, the Copper Matt. Essentially a version of his Bead, Hare, and Copper with a peacock herl head and heavier wire ribing, Parks’ Fly Shop has been stocking the Copper Matt in larger sizes for at least ten years, to modest sales at best. This year I happened to tie a few in smaller sizes in my box, probably due to guiding on the lower Madison during heavy caddis hatches and having strong success with them earlier in the season. The smaller size (#16) seemed to be the ticket. The fish loved this one this year. Let’s hope they do next year. My new fly tying vid for the pattern is embedded below.
