Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
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.
