Zapada cinctipes (Tiny Winter Black) Stonefly Nymph Zapada cinctipes (Tiny Winter Black) Stonefly Nymph

Dorsal view of a Zapada cinctipes (Nemouridae) (Tiny Winter Black) Stonefly Nymph from the Yakima River in Washington

Nymphs of this species were fairly common in late-winter kick net samples from the upper Yakima River. Although I could not find a key to species of Zapada nymphs, a revision of the Nemouridae family by Baumann (1975) includes the following helpful sentence: "2 cervical gills on each side of midline, 1 arising inside and 1 outside of lateral cervical sclerites, usually single and elongate, sometimes constricted but with 3 or 4 branches arising beyond gill base in Zapada cinctipes." This specimen clearly has the branches and is within the range of that species.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Exploring some new water on the Henry's Fork of the Snake

By Troutnut on September 24th, 2021

On the way to my first elk hunt in Wyoming, I planned a morning stopover along the Henry's Fork of the Snake. I figured there wouldn't be much hatch activity, and I wanted to try something new anyway, so I skipped the famous Harriman Ranch section where I normally fish (and collect bugs), and I explored some new water farther downstream, in a place that took some hiking to reach. I brought rods to fish streamers and nymphs, and both were effective.
